I just downloaded and dearchived android SDK for Windows. I`m currently using W8 64x.

The error message points to a problem with your Java version. Do you have a JDK installed?
Try adding the following (noting the new line):
/!\ make sure, that the -vm option occurs before the -vmargs command.
Everything after -vmargs is passed directly to the JVM.
-vm
c:/wherever/java/jdk1.6.0_21/jre/bin/server/jvm.dll
-vmargs...
...to your eclipse.ini file, pointing to the JDK you want to use, and check that the required Java version is at least as new as your JDK. This is the path for a Windows system. More on paths can be found here (scroll down).
If you don't know where the eclipse.ini file is: regularly it is in the folder of your eclipse.exe.
Edit2: #KadoLakatt: the reason why installing the latest Java Version worked for you is because Eclipse checks the standard path for a JVM if it doesn't find a -vm entry (see here). However I'd not recommend that, since you might be wrong guessing the JVM used. If you update Java (automatically?) you might run into problems in your Eclipse wondering what you might have changed. Better set it to a specific folder in your eclipse.ini to be certain.

I received this error out of the blue. Eclipse stopped working even though I made no config changes and did not install any new jdk's.
Here was my eclipse.ini file :
--clean
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar

To get Eclipse to start successfully I removed

So here is my updated file :

I have no idea why removing osgi.requiredJavaVersion=1.6 fixed this as my jvm version is 1.6. From the doc http://help.eclipse.org/indigo/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html
osgi.requiredJavaVersion
The minimum java version that is required to launch Eclipse. The default value is "1.4.1".
I think my java version was set correctly. Anyway Eclipse starts and runs for me now......

it can be like this as well:
-vm
C:\Program Files\Java\jre6\bin\server\jvm.dll

Working combinations of OS, JDK and eclipse bitness.
32-bit OS , 32-bit JDK , 32-bit Eclipse (32-bit only)
64-bit OS , 32-bit JDK , 32-bit Eclipse
64-bit OS , 64-bit JDK , 64bit Eclipse (64-bit only)
Kindly use 1 of the above combinations.

Adding -vm parameters works for me.
-vm
C:\Program Files\Java\jdk1.7.0_45\jre\bin\server\jvm.dll

For those of you who tried all the above answers without any success, try lowering your -Xms value. I am required to support an older Eclipse (Weblogic Eclipse 10.3.6) - I had the following .ini on my Windows 7 machine and my Windows Server 2008 R2 Enterprise VM (the Java version below points to a 32-bit Java) that had worked and were working perfectly, respectively.
-vm
C:/Java/Java7/jdk1.7.0_79/bin/javaw.exe
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813

-Xmx1024m
-XX:MaxPermSize=256m
-Dsun.lang.ClassLoader.allowArraySyntax=true
-Dweblogic.home=C:/Oracle/Middleware/wlserver_10.3
So a 32-bit Java for a 32-bit Eclipse, but still exit code 1. Based on all answers I had seen here, and the only change being a new laptop with Windows 10, the only possible explanation was that the new OS and the Eclipse were disagreeing on something. So I started playing around with each of the values, and it worked when I lowered both Xms and Xmx to 512m. I have a hunch that possibly the new Windows OS is preventing a higher initial heap size based on some run condition (the higher -Xms does work on Windows 10 on all other similar devices I came across) - so any other explanation is welcome. Meanwhile following is the only value I tweaked to successfully launch Eclipse.
-Xms512m

I've encountered similar problems. The reason is that the path to my eclipse includes Chinese characters. Once those characters are deleted, the problem is solved. Please check if there are characters other than English in your path.

I had same issue in my windows 7, 64-bit machine. Then I downloaded and installed 64 bit jdk for Java(which includes jre). This solved the issue.

I too faced the similar issue , not solved after adding the command in eclipse.ini file. My root cause is different. I was experimenting on sequence diagrams using objectaid. This is throwing an exception and disturbed my workspace. You may have different issue when working on new plugins. Better you check the log file located in your project work-space C:\path\to\workspace\.metadata\.log

This can be resolved by adding the following line to the eclipse.ini file
-XX:-UseCompressedOops

I had the same issue which was caused due to crash shutdown of my windows 10. Earlier in the path I had Oracle path ie the path inserted by Oracle at the time of installation of JDK. I removed it and changed the path to the JDK location. This solved the problem.

Mine is a 64 bit system with 64bit java installation.
what worked for me was the following:
Goto the eclipse installation directory
right click the eclipse icon and click "send to desktop as shortcut"
Then right click on the shortcut icon in the desktop and then > properties > shortcut tab
In the target field point it to the correct java 64 bit installations home path using the vm argument with the java_home path enclosed in quotes like so :
D:\Scala_eclipse\eclipse.exe -vm "C:\Program Files\Java\jdk1.8.0_11"
This almost always solves all my Eclipse (scala eclipse as well) related problems.
As mentioned in the answer , please make sure you are using the right combination of eclipse and java

If you have java 8 installed it might be related to the following issue:
https://support.oracle.com/knowledge/Middleware/2412304_1.html
Simply removing/renaming the "C:\Program Files (x86)\Common Files\Oracle\Java\javapath" worked for me.

Directly changing eclipse file is not a good idea, no matter facet or ini, unless it could be changed in eclipse. Had the same problem, with jdk1.8 installed. Change it to jdk 1.7.
Besides, according to https://wiki.eclipse.org/Eclipse/Installation, both LUNA and MARS need 1.7. So just ensure you have it installed.

1 ) Open the SpringToolSuite4.ini File.
2 ) Search For the openFile.
3 ) Provide the jvm.dll file location in SpringToolSuite4.ini
4 ) Note : Provide the New Line between -vm and your jvm.dll file location path.as shown below.
openFile
-vm
C:\Program Files\Java\jre8\bin\server\jvm.dll
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Xms256m

i had Java Run time environment and Java SDK both on my machine. I removed Java Run time environment and it resolved my error.
Earlier this error, i was using elipse with Java SDK only and later had installed JRE specifically for one need.

just to add here...For the guys those who still couldn't start eclipse due same error, please check eclipse.ini file again and see have you forgot to put M after memory size.
For example:
-Xmx1024
or
-Xmx1024MB
or
-Xmx1024 M
or
-Xmx1024 mb
or
-Xmx1024mb
are incorrect, it should be -Xmx1024M. I have been trying different ideas from SOF and from other forums, and in this cut/paste I forgot that I missed M (such a little thing to miss), so I thought I should share. If it works for some of you please up-vote.

I had this issue recently, but I hadn't changed any java or updated the java version, May be this issue happened because of crash shutdown of the system.
And after reading a couple of answers here I decided to change the java version from 1.6 to 1.7 in the eclipse.ini file.
-vmargs
-Dosgi.requiredJavaVersion=1.6
After this change the Eclipse started well and it worked. Since I didnt had changed anything i decided to change it back to 1.6 to what it was originally.
Then I started eclipse and guess what it worked. So Looks like in my case just touching/modifiying the eclipse.ini file worked.
I hope this answer is helpful to somebody.

If none of the solutions works, please check if you have more than one version of java installed on your machine. Please keep only one version which you prefer and everything should work fine.

None of the above answers helped for me. I discovered that, in general, an error like that could mean that your eclipse.ini has an invalid entry. So, all the above answers could be correct, depending on your particular case. In my case, it turned out I added a locale argument with a typo in it.

I tried to change the path in the parameter -vm, but it did not help. Then I deleted the parameter -vm and -vmargs from the eclipse.ini.
It worked for me

My path of -javaagent argument was having Spacial characters like '&'. I placed the Lambok jar in different place and gave the path to that place. It worked for me.
previously it was
-javaagent:C:\Software & Tool\lambok.jar
i changed it to
-javaagent:C:\Labmok\lambok.jar

Please check your computer and if Java JRE not install download and install it.
https://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
If install please check is it 32 bit or 64 bit as per your operating system
To check for 32 or 64-bit JVM, run:
$ java -d64 -version
$ java -d32 -version
Error: This Java instance does not support a X-bit JVM.
Please install the desired version.

Open the Eclipse Installation Folder on Windows Machine
Find the eclipse.ini
Open the eclipse.ini File and add the below two lines before -vmargs
-vm
C:\Users\IshaqKhan\jdk1.8.0_173\bin\javaw.exe

This work for me in eclipse js and eclipse php:
-vm
C:/java/jdk-11.0.1/bin/javaw.exe
--launcher.appendVmargs
-vmargs

I had a similar issue. I opened my eclipse.ini file and noticed that I configured at the end some lines for the lombok library in the past. The path to my lombok jar file was no more valid. After correcting it, my eclipse was working like a charm again. In conclusion, my piece of advice would be to verify that all the paths configured in this file are valid.
eclipse.ini :
-...
-javaagent:C:\some\path\to\lombok.jar
-Xbootclasspath/a:C:\some\path\to\lombok.jar

JAVA Path could be incorrect
Trying above solution didn't help me.
So i checked java --version on command prompt, which gave virtualization conflict. It seemed installation of virtualization software on system had messed up environment variables.
Hence I checked JAVA_HOME which was on correct path, then checked system variable PATH which had correct JAVA bin path as well, so removed 'C:\Program Files (x86)\Common Files\Oracle\Java\javapath' and checked java --version on command prompt again, which gave correct value and also fixed above issue of eclipse start.

On Windows 10, removing
-XstartOnFirstThread
from the eclipse.ini fixed the issue for me

Go to eclipse folder and then go Configuration Setting file
change the below path under -vm tag in config file
Note- you need to mention new java path with bin and then javaw.exe like below
-vm
java path/bin/javaw.exe
It should work. Thanks.

if it says
c:/program files/java/jre/bin/server/jvm.dll not found
then copy the jre from jdk folder and paste it outside the jdk folder . and then try again...

How to fix Eclipse Java Virtual Machine Launcher Error?

So like the title says, Im having an issue with eclipse JVM launcher. Last night, everything was working fine, as far as I know, nothing at all has changed on my pc since then. However, I woke up this morning to find that when I run any of my projects in eclipse I recive this error: Java Virtual Machine Launcher- Error: could not open C:\Program Files\Java\jre1.8.0_60\lib\amd6jvm.cfg
I have already verified the integrity of my Path variable, (C:\Program Files\Java\jdk1.8.0_65\bin) Now at this point, you may notice, my jdk is on version 65. So is my JRE and java installation. I dont understand why eclipse is using jre 60. I also checked the preferences and changed the jre version too 65. No luck. Furthermore, I ran a simple java file without using eclipse through the command line and that ran/compiled just fine. I tried adding the -vm tag (It didn't already exist there) to eclipse.ini and setting it too the jvm but it didn't help. (I than removed it) I have no idea what to do... Please help, I've tried everything I know how to do. Thanks!

EDIT 2
I have already tried reinstalling java, eclipse and jdk.

For windows user, if your getting this error:
Java Virtual Machine Launcher- Error: could not open C:\Program
Files\Java\jre1.8.0_60\lib\amd6jvm.cfg
it indicates there is no jre1.8.0_60 version in your system. So you need to set the JRE version which is already there in our system by executing the below command:
Go to cmd prompt
go to the eclipse folder (which you have installed) by executing:
cd eclipse-folder-path
execute below command: eclipse -vm jre_path
ex:
eclipse -vm "C:\Program Files\Java\jdk1.8.0_131\jre\bin\javaw"

Ok, so after a bit of digging, I managed to fix the problem. In eclipse, I went to Windows>Preferences>Java>Installed JREs>Execution Enviorments>JavaSE-1.8>Compatible JREs>jre1.8.0_65(perfect match). I have no idea why or how that changed, (or why it worked) but hey, I'm not complaining. For anyone else with the same issue, first do everything I said in the question body, then try this. It hopefully will work for you too.
EDIT:
I just figured out the cause of the issue as well. I opened the workspace on another computer (my workspace is on a shared drive) running java 1.8.0_60 while this computer is running java 1.8.0_65. Obviously, eclipse had to change the version therefore causing problems.

Simply removing/renaming the "C:\Program Files (x86)\Common Files\Oracle\Java\javapath" worked for me.

Directly changing eclipse file is not a good idea, no matter facet or ini, unless it could be changed in eclipse. Had the same problem, with jdk1.8 installed. Change it to jdk 1.7.
Besides, according to https://wiki.eclipse.org/Eclipse/Installation, both LUNA and MARS need 1.7. So just ensure you have it installed.

1 ) Open the SpringToolSuite4.ini File.
2 ) Search For the openFile.
3 ) Provide the jvm.dll file location in SpringToolSuite4.ini
4 ) Note : Provide the New Line between -vm and your jvm.dll file location path.as shown below.
openFile
-vm
C:\Program Files\Java\jre8\bin\server\jvm.dll
-vmargs
-Dosgi.requiredJavaVersion=1.8
-Xms256m

i had Java Run time environment and Java SDK both on my machine. I removed Java Run time environment and it resolved my error.
Earlier this error, i was using elipse with Java SDK only and later had installed JRE specifically for one need.

just to add here...For the guys those who still couldn't start eclipse due same error, please check eclipse.ini file again and see have you forgot to put M after memory size.
For example:
-Xmx1024
or
-Xmx1024MB
or
-Xmx1024 M
or
-Xmx1024 mb
or
-Xmx1024mb
are incorrect, it should be -Xmx1024M. I have been trying different ideas from SOF and from other forums, and in this cut/paste I forgot that I missed M (such a little thing to miss), so I thought I should share. If it works for some of you please up-vote.

I had this issue recently, but I hadn't changed any java or updated the java version, May be this issue happened because of crash shutdown of the system.
And after reading a couple of answers here I decided to change the java version from 1.6 to 1.7 in the eclipse.ini file.
-vmargs
-Dosgi.requiredJavaVersion=1.6
After this change the Eclipse started well and it worked. Since I didnt had changed anything i decided to change it back to 1.6 to what it was originally.
Then I started eclipse and guess what it worked. So Looks like in my case just touching/modifiying the eclipse.ini file worked.
I hope this answer is helpful to somebody.

If none of the solutions works, please check if you have more than one version of java installed on your machine. Please keep only one version which you prefer and everything should work fine.

None of the above answers helped for me. I discovered that, in general, an error like that could mean that your eclipse.ini has an invalid entry. So, all the above answers could be correct, depending on your particular case. In my case, it turned out I added a locale argument with a typo in it.

I tried to change the path in the parameter -vm, but it did not help. Then I deleted the parameter -vm and -vmargs from the eclipse.ini.
It worked for me

My path of -javaagent argument was having Spacial characters like '&'. I placed the Lambok jar in different place and gave the path to that place. It worked for me.
previously it was
-javaagent:C:\Software & Tool\lambok.jar
i changed it to
-javaagent:C:\Labmok\lambok.jar

Please check your computer and if Java JRE not install download and install it.
https://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html
If install please check is it 32 bit or 64 bit as per your operating system
To check for 32 or 64-bit JVM, run:
$ java -d64 -version
$ java -d32 -version
Error: This Java instance does not support a X-bit JVM.
Please install the desired version.

Open the Eclipse Installation Folder on Windows Machine
Find the eclipse.ini
Open the eclipse.ini File and add the below two lines before -vmargs
-vm
C:\Users\IshaqKhan\jdk1.8.0_173\bin\javaw.exe

This work for me in eclipse js and eclipse php:
-vm
C:/java/jdk-11.0.1/bin/javaw.exe
--launcher.appendVmargs
-vmargs

I had a similar issue. I opened my eclipse.ini file and noticed that I configured at the end some lines for the lombok library in the past. The path to my lombok jar file was no more valid. After correcting it, my eclipse was working like a charm again. In conclusion, my piece of advice would be to verify that all the paths configured in this file are valid.
eclipse.ini :
-...
-javaagent:C:\some\path\to\lombok.jar
-Xbootclasspath/a:C:\some\path\to\lombok.jar

JAVA Path could be incorrect
Trying above solution didn't help me.
So i checked java --version on command prompt, which gave virtualization conflict. It seemed installation of virtualization software on system had messed up environment variables.
Hence I checked JAVA_HOME which was on correct path, then checked system variable PATH which had correct JAVA bin path as well, so removed 'C:\Program Files (x86)\Common Files\Oracle\Java\javapath' and checked java --version on command prompt again, which gave correct value and also fixed above issue of eclipse start.

On Windows 10, removing
-XstartOnFirstThread
from the eclipse.ini fixed the issue for me

Go to eclipse folder and then go Configuration Setting file
change the below path under -vm tag in config file
Note- you need to mention new java path with bin and then javaw.exe like below
-vm
java path/bin/javaw.exe
It should work. Thanks.

if it says
c:/program files/java/jre/bin/server/jvm.dll not found
then copy the jre from jdk folder and paste it outside the jdk folder . and then try again...

Setting up Eclipse with JRE Path

I have downloaded and extracted Eclipse. I have Eclipse in the following directory: C:\Applications\eclipse. When I try and run the executable , I get the following message :
I currently have the following folder:
C:\Program Files (x86)\Java\jre7
Do I need to set up some environment variables for my Windows 7 OS to get Eclipse to run ? If so , may I please have some help to do this ? If not , can I please have some help to get Eclipse to run .
EDIT
I have changed the shortcut to include the path to the Virtual Machine , and am now getting this error :
http://www.canning.co.nz/Eclipse/Eclipse_Message2.png

You can add this line to eclipse.ini :
-vm
D:/work/Java/jdk1.6.0_13/bin/javaw.exe <-- change to your JDK actual path
-vmargs <-- needs to be after -vm <path>
But it's worth setting JAVA_HOME and JRE_HOME anyway because it may not work as if the path environment points to a different java version.
Because the next one to complain will be Maven, etc.

Add this to eclipse.ini:
-vm
your_java_path\bin\javaw.exe
...but be aware that you must add these lines before -vmargs

I have several version of JDK (not JRE) instaled and I launch Eclipse with:
C:\eclipse\eclipse.exe -vm "%JAVA_HOME%\bin\javaw.exe" -data f:\dev\java\2013
As you can see, I set JAVA_HOME to point to the version of JDK I want to use.
I NEVER add javaw.exe in the PATH.
-data is used to choose a workspace for a particular job/client/context.

Add the following -vm D:/Java/jdk1.6.0_30/bin/javaw.exe in the begin of eclipse.ini like this :
-vm
D:/Java/jdk1.6.0_30/bin/javaw.exe
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20130327-1440.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20130807-1835
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms1024m
-Xmx2048m

This may sound dumb, but it may be a fresh, or damaged install, so is the JDK installed? If not, go to the download site and download the latest version of Java JRE. Like I said, this may sound dumb, but it solved my problem.
http://www.oracle.com/technetwork/java/javase/downloads/index.html

You should specify where Eclipse should find your JDK in the file eclipse.ini. Specifically, the following parameter (note that it is 2 separate lines in the ini file):
-vm
C:\Java\JDK\1.8\bin\javaw.exe
or wherever your javaw.exe happens to be.
Note: The format of the ini file is very particular; make sure to consult https://wiki.eclipse.org/Eclipse.ini to ensure you get it exactly right

Add the following to the eclipse.ini :
-vm
Java_Home_Variable\bin\javaw.exe
In my Case its
-vm
H:\usr\java\jdk1.6.0_16\bin\javaw.exe

I had the same issue caused by two things:
I had downloaded a 32bit Java version instead of 64bit.
The eclipse.ini did not have path to javaw.exe, so as per prior posts added the statement which points to the location java.
So after I uninstalled the 32 bit Java 1.7, installed the correct one and added the javaw.exe path, eclipse fired up with no more errors

You are most probably missing PATH entries in your windows. Follow this instruction : How do I set or change the PATH system variable?

I just copied the jre folder to whatever path the message tells me it was missing at, and solved it.
(after editing the JAVA_HOME and editing the eclipse.ini didn't worked (as i probably did something wrong)) (i have no other java applications running so it's not affecting me)

If you are using windows 8 or later:
download and install the jdk or jre with all the default settings and options.
Then download and install eclipse.
Everything should work fine. I don't know if it works exactly the same for other OS, but you don't have to set the PATH manually in Windows 8 or later.

Java version used : 1.8
IDE : Eclipse Neon
Adding like the below didn't work for me
-vm
[relative java home]/jdk1.8.0_21/bin/javaw.exe
and then when i removed
javaw.exe
it worked, so it will be like
-vm
[relative java home]/jdk1.8.0_21/bin/

Eclipse Juno with JRE 7 causes problems on startup

The issue that is explained seems to be a common one and different solutions have been proposed already, many of which work. One example of this discussion can be found here.
My question is more about why rather than how.
We have been wrestling with this issue here ourselves as well and found that if we launch eclipse using javaw.exe the problem occurs, but if we invoke Eclipse using jvm.dll the problem does not appear. Even though in both cases the eclipse.ini remained same.
To explain my case I will use the example of launching eclipse.exe from command line with a single -vm argument. For reference below is the eclipse.ini that we are using:
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20120522-1813
--launcher.XXMaxPermSize
256m
-vmargs
-Xms128m
-Xmx1280m
-XX:MaxPermSize=512m
-Dderby.stream.error.field=java.lang.System.err
You can see that the memory requested for allocation is quite a lot for both heap (1280m) and PermGen (512m). If you are unable to reproduce the issue you can try increasing the memory until the error occurs.
There are three different command lines that you may use:
eclipse.exe -vm ..\jre\bin\javaw.exe
eclipse.exe -vm ..\jre\bin
eclipse.exe -vm ..\jre\bin\client\jvm.dll
Only the first one causes the error (javaw.exe). The remaining two options launch eclipse successfully. Reducing memory requirement in eclipse.ini also fixes the problem obviously.
So my question is, why does javaw.exe fail when the other two command lines work? What is the difference between choosing these different paths? Does one enforce parameters more strictly than the others?
Environment: Eclipse: 3.8-win32, JRE: 7u7-win32, Windows 7 x64

I can't explain why pointing Eclipse to the executable fails but the dll does not, but I can offer this to explain the problem. The gist of it is that on Windows, the JVM needs to allocate a contiguous chunk of memory for your heap, and if it can't then it fails to start.
Perhaps this page will help figure out why pointing to the dll seems to work. Otherwise, I'd ask on the Eclipse Equinox forum.
