I am trying to use Eclipse on a friends computer but we keep getting this when we run Eclipse
We have the environmental variable set as well.
Edit
it was working before he installed the black berry plug in.
The variable JAVA_HOME is not required by Eclipse. If your Java installation does not put the Java executables in the PATH, you should add those manually.
A faster way to have your Eclipse up and running consists in modifying the eclipse.ini and using the -vm option.
http://wiki.eclipse.org/Eclipse.ini#-vm_value:_Windows_Example
I had the same problem. For me, I needed the JDK. So I had to install the JDK. It should match the build platform that is, 64bit vs. 32bit windows. After that, I removed, the -vm line from the eclipse.ini file (the suggested fix). It was giving me the "Can't create virtual machine" error. The current release of JDK is version, 7 whereas the Android Developers Toolkit version of eclipse is currently based on JDK 6. But it seems to work. Eclipse came up and is functional. Haven't actually written a program yet.
Go to eclipse folder (where eclipse is installed) and open eclipse.ini file in your editor and add the following code after openFile tag.
-vm C:\Program Files\JDK6\bin\javaw.exe
That's all.
I had a similar problem, since our Java and JDK is consistently updated by our service desk, including uninstalling old JDKs. They take care of the PATH for us, but then the JRE that Eclipse was used to "seeing" was gone. So, the thing that has worked best for me is to modify the shortcut's "target" from:
"C:\Program Files\Eclipse\Eclipse IDE for Java EE Developers\eclipse.exe"
to
"C:\Program Files\Eclipse\Eclipse IDE for Java EE Developers\eclipse.exe" -vm "C:\Program Files\Java\<jdkver>\jre\bin\javaw.exe"
That will point Eclipse toward to the JRE in the JDK you want it to use, and then you can update that shortcut when your JDK updates.
This is on Windows 64bit, obviously.
It can also happen on mismatch of JAVA and Eclipse bit version.
for eg:
If in your System java is 32 bit and you are trying to install Eclipse of 64 bit then the same situation might occur.
Because Eclipse will look Java in Program Files while at the same time Java may be present in Program Files (x86).
So in this case eclipse will not get java and throw the same error.
While installing eclipse, Jre missing :
I solved my error as follows:-
This error may comes if you have 2 program files folder in your system.
"Program files" &
"Program files x86".
Please install JDK&JRE in the "Program files" folder.
Hope your jre missing error get solved.
this works for me:
open eclipse.ini file in your editor and add the line: -vm C:\Program Files\JDK11\bin\javaw.exe
update system PATH with correct JDK path.
I recently decided to start trying Android app development, so I downloaded the Java SE Development Kit 8 (x86) for Windows (I got Windows 8 64bit, but my guide recommends getting the 32bit one), the Android SDK, and the Eclipse IDE for Java Developers (x86).
However, my Eclipse won't launch when I double click eclipse.exe! Instead, I get the following error message:
I tried adding Java to my Path variable in my Environment variables as suggested in some of the solutions I looked up, but it still doesn't launch properly.
Anyone know what else I can try? Also, if possible, please do not use super-technical vocabulary as I'm new to these kinds of stuff and will not understand you...thank you haha :D
I had the same issue and was trying to install different versions of JDK: 1.6, 1.7, 1.8.
It didn't help much.
The problem was resolved when I changed PATH variable by removing
C:\ProgramData\Oracle\Java\javapath;
In command prompt I also ran following commands:
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25
set PATH=C:\Program Files\Java\jdk1.8.0_25\bin;%PATH%
But I think the most important was to remove C:\ProgramData\Oracle\Java\javapath; from the PATH.
I know exactly how to solve your problem. Go to search and put in environment, a prompt will come up and ask you to "Edit environmental variables for your account" click that and a window will pop up. There will be the current paths which are running on the top (you should have your JDK version running, mine is 1.8) and on the bottom part there will be paths to choose from. Select (on the bottom part) the java path and delete it, then click okay. This should work.
If it didn't work, You may also add a new path to the java bin folder which worked for me.
Here is an alternative:
As described here, make sure that you have the -vm option set in your eclipse.ini file.
It must be an absolute path and on 2 separate lines:
-vm
<Absolute Path>\javaw.exe
Save your .ini and relaunch Eclipse
One line answer, remove 'C:\ProgramData\Oracle\Java\javapath;' from your path variable. It will start to work.
Most errors with starting eclipse happen due to multiple JRE or JDK version which makes the installer go nuts.
Solution: Go to Control Panel -> Uninstall Programs
If you're running 64-bit java, then uninstall all Java without the 64bit indicator. If 32-bit, then uninstall all that have 64-bit
It works like magic!
What worked for me was having installed adoptopenjdk11 using Chocolatey package manager:
choco install adoptopenjdk11
Can anyone please tell me why I get the following error when I try to run my Java programs? The programs get compiled successfully but are not able to be run. I have already set the path of Java.
C:\JavaServ>javac hello1.java
C:\JavaServ>java hello1
Error: could not open C:\Program Files\Java\jre6\lib\amd64\jvm.cfg
Don't think if this is a correct way...(perhaps proper installation of Java is a permanent solution)....but this is a trick..:)
Delete the “java.exe” file from “c:\windows” and “c:\windows\system32″. That should fix it.
In case you get here and scroll this far down, the newer Oracle versions of Java x86 and probably also x64 are horribly broken. You may find that after removing all versions of Java, and even manually deleting all the versions you find in c:/program files/ and c:/program files (x86)/ that you still can't properly run a fresh install of Java.
I'm here to tell you why, and how to fix it.
Go to C:\Program Files\Common Files\ and DELETE the Oracle directory. It has a version of Java underneath it inside a junction (symlink) that is sequestered away from all your other installs. Bastards.
Now, also go to System Properties -> Advanced -> Environment Variables and edit the PATH under System Variables. Find the place where the Oracle folder is referenced, and delete it. Close all your windows down, reboot to be extra sure if you want.
Install the JRE or JDK. Open a command prompt and type 'java' and if it comes up, you're golden. If not, go back to the PATH variable and add "C:\Program Files (x86)\Java\jdk1.8.0_221\bin" or whatever looks right for your machine.
I hate Oracle.
this should be an internal file of JRE and in general you shouldn't deal with it when you're running/compiling java.
Here you can find an explanation of what exactly this file is intended for.
Bottom line, your Java installation is somehow corrupted, so as a first resort to resolve this issue, I suggest you to re-install jre.
You should ensure that you're installing the right jre for your architecture.
Hope, this helps
You can not Uninstall/Reinstall JRE if you are having this error.
That's why because previous installation has copied 3 files namely Java.exe, Javaw.exe, javaws.exe in the c:/windows/system32 folder.
Simply go there and remove these files and download a fresh version of jre from oracle and install it. I will prefer JDK 1.6 update 45. Which is very stable.
update registry path to installation location
This happened for me when I moved out my default installation from an overcrowded primary partition to another location. Fir
Java mysteriously broke on my work PC after a security patch was pushed out to us, giving this error whenever you tried to run a Java program. Somehow the 'lib' subdirectory of the Java 7 install had vanished! It might have been related to having multiple Java versions installed simultaneously.
If you're getting this error there are basically two things that could be wrong:
1) Your Java installation is broken. If the file/directory it's complaining about doesn't exist, uninstall and reinstall the JRE and then it should be there. This fixed it for me.
2) If the files are there, your PATH is somehow incorrect or pointing at an old/broken Java install. In this case you either need to fix your PATH to point to the correct java.exe/javaw.exe, or use a fully qualified path. So instead of:
java <whatever>
Use
c:\<full path to correct JRE>\bin\java.exe <whatever>
3) If your PATH is correct and files are there and it's still failing, the path could be getting truncated because it is too long. see: Running Java gives "Error: could not open `C:\Program Files\Java\jre6\lib\amd64\jvm.cfg'" .
i also had the same issue due to one more instance of java,javaw and javaws in C:\Windows\System32 which was pointing to jre6 and my default location of jre was pointing to this(C:\Windows\System32) location. Even having jdk 1.8 as my JAVA_HOME location i were getting this problem.
so either remove or rename java,javaw and javaws it will work.
If you have installer deployed Java on Windows and decided to bring some order to your JDKs with folders moving...
All answers with java.exe in Windows\System32 are right but in more tough situation - there are no files, but error messages still happen, then remember about Windows Registry entries (look regedit.exe).
They store information about JRE folder in this registry key:
win32:
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
win64:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Runtime Environment
The program can be compiled but while running it leads to such an error:
Could not open C:\Program Files\Java\jre6\lib\amd64\jvm.cfg
It indicates that the jvm.cfg file is missing in Program files. Reasons may be file corruption or file may be deleted. Install JRE again in "Program Files" folder.
Another case which happened with me is that I installed 32 bit jdk & jre in my 64 bit system in Program Files(x86) and my Program Files folder was empty. That was the reason for that error. So I installed 64 bit JRE in Program Files folder and it started to work. Note that it is not related to jdk version. Associated with only JRE problem.
I was getting the same error with my docear program on windows 7.
What I found is that I had two instances of java 1.6 installed on my computer. One instance has a jvm.cfg and the other does not.
Modifying my path to search the correct instance of java (in bold) first fixed the problem.
Here is my corrected path:
C:\Users\kranjit>path
PATH=C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32
\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Enterprise Vault\EVClient\;C:\Program Files\Java\jre6\bin;C:\Program Files (x86)\Java\jre6\bin;
In our system, for "java(jre)" for runtime purpose is availed, So If you install any different version of java, propbably the version before the one which is already installed.
E.g.; my windows 8.1 I have runtime java version of 8, then when I install Ver7 it is bu default taking V8, yet I uninstall 8, In this kind of Scenarios, Removing java.exe from c:\windows\system32 makes my java runtime work
For anyone still having an issue I made mine work by doing this probably not the best fix but it worked for me..
I uninstalled all Java's that i current had installed, reinstalled the latest one and changed the install directory to C:/Windows/jre (Basically where it kept saying there was no config file)
If you have installed more than one jdk version , uninstall the others and keep only the one in use. this worked for me.

I want to add some pointers here.
Whenever you face the error saying Could not open jvm.cfg, it means that there was some mess happened with java installation path. Below approaches might help.
If java is added in environment path, then open command prompt and type where java. If you get list of directories where java path specified. Other than the directory where you need the java file, delete the java files in all other directories.
If you are reading 2nd pointer, then 1st pointer might have not helped. Type regedit in run dialog and under HKEY_LOCAL_MACHINE, go to softwares/javasoft and rename the paths of the java installed directory.
Let me know if above approaches solve the problem.
The simple Solution is just uninstall the javaSE and reinstall it to the default location.
Then copy the installed location probably like C:\Program Files\Java\jdk1.8.0_131\bin.
After then go to desktop then while selecting right click on My Pc or This pc shortcut the under that select properties >> Advanced system settings >> under Advance tab >> last option Environment Variables..>>path >> edit >> past >> ;(not required if win10)/(required if windows 7)
I had this issue when installing 201, somehow it didn't uninstall my 191 properly. I had to go to the Program Files/Java folder, rename the old 201 directory, then install a fresh copy of 201. When doing so, it prompted me to uninstall 191, which I did. Now it's working fine.
I was facing the same issue after upgrading my java version.I had more than one jdk installation. I have manually uninstalled the old jdk version . Then it worked for me.
Resolved
I had similar issue, I tried different things but nothing worked. Then when I checked the installed programs. I could see two versions of java installed.
What I did is, just uninstall all java versions and freshly installed the required version. But this didn't seem to work when I checked in terminal. Then I had to reopen the terminal and run the command, then only it worked.
Note : Dont forget to reopen the terminal if you are testing via terminal.
I had an identical error trying to start IntellJ with a custom JBR.
C:\Users\user>"C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2021.3.3\bin\idea.bat"
Error: could not open `C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 2021.3.3\jbr-arm64\lib\jvm.cfg'
This issue may occur if there were problems extracting Java or OpenJDK from a zip or tarball (e.g. a slow extraction was terminated prematurely) or if the zip or tarball was corrupted or incomplete.
If caused by a corrupted zip or tarball, try redownloading the archive.
If caused by a bad extraction, repeating the extraction will fix this.
Copying and pasting i386\jvm.cfg from a different PC will resolve the issue.
I had the same issue.I just uninstalled Java and reinstalled again it worked fine after that . The problem is related to JRE so you can just reinstall JRE.
I had same problem - when I tried to run a Java program from command line the error message appeared: "Error: could not open jvm.cfg".
My Path environment variable included following path:
C:\ProgramData\Oracle\Java\javapath
In the folder there were 3 exe files:
java.exe
javaw.exe
javaws.exe
When I removed the the entry
C:\ProgramData\Oracle\Java\javapath
from the Path environment variable and restarted cmd, I could run the program as usual (java MyProg).
Obviously I have corrupted the path pointing to correct java jre installation
C:\Program Files\Java\jre1.8.0_151
somehow previously when I played with my settings.
It means that this jvm.cfg file is not found. Maybe it was deleted. Reinstall the program. If you have this problem with a game for example, reinstall Java in the games folder, or copy Java files .de c:/Program Files/JAVA and paste to the JAVA folder in the game folder
I am trying to work with Eclipse Helios on my x64 machine (Im pretty sure now that this problem could occur with any eclipse) but it just doesn't cooperate.
When I try to run eclipse I get the following:
I have installed
Helios EE x64 (latest version)
JDK 1.6.025 (x64)
I have linked my Environment Variables up correctly and tried to compile a Java file through cmd and have succeeded.
Whenever I tried running eclipse i get exit code=13 (required java version=1.5)
I tried running the following in cmd:
-vm "mypath\jdk1.6.025\jre\bin"
command as forums suggested
as well as other paths
-vm "mypath\jdk1.6.025\bin"
-vm "mypath\jdk1.6.025\jre\bin\javaw.exe"
even
-vm "mypath\jre6\bin" out of desperation
to no avail.
I am all out of ideas and I wonder if anybody had this problem. I even downloaded the helios x86 version and x86 JDK version yet it did not fix the problem. (I changed the environment variables)
I changed everything back but I'm stuck...
Related Question: Cannot Run Eclipse
It turns out that a directory had an ! in its name and eclipse had a problem with that.
Once I switched the directory (from Desktop which is located in the user directory which had ! in it to C:/ ) everything worked fine. (look at the Djava.class.path in the image located in my the question above for the whole path - it should make it clear what the problem was)
Vista allows you to create a username that contains ! character and then a lot of programs have issues with it
Update
If somebody is still getting this problem even though their path is ok I suggest
trying to look at the Environment Variables
then try uninstalling the Helios EE ( or any other version of ee you are running ) and JDK and then reinstalling the 86x versions of both (they should still work on the 64x platform).
for further explanation look here
Thank you everybody that tried to help
Please, check that your have downloaded the x64 version. ;)
And your installed Java, is x86. Use Eclipse x86 if you use Java x86.
Because your eclipse's env-arch was not matched with java-arch, for instance: eclipse-64bit run in java-32bit or vice versa.
In Windows: Set correct env path to the specific 32 or 64bit java acording to eclipse.
In Linux:
Try run: [path-to-eclipse]/eclipse -vm [jdk-path]/bin
What version of java is on your path when you start eclipse? Try entering java -version on a command prompt. You will want Sun java 1.5 or higher. See http://www.ehow.com/how_4784069_terminated-exit-code-error-eclipse.html
This turned out to be a permissions error for me. I change the kepler folder, eclipse root directory to have permissions set to everyone all. This is going to be a security risk so I will need to set the permissions to be program specific. using procmon.exe I found that javaw.exe was getting write permissions denied. The programmers of eclipse and javaw.exe did not give those programs elevated permissions to run as trustedinstaller.
I faced the same problem
Turned out my Java version in the PATH had been updated to 1.8
Once I changed this back to 1.7, my Eclipse started without issues
I just installed Eclipse 3.5. Before I could install the Android Plugin I needed to install a Java jdk, which I did. After restart Im not able to start Eclipse anymore, because I receive the following error:
Error: could not finde Java 2 Runtime
Environment
The weired thing is, that now I cant even open my other Eclipse Installations, that I use for PHP Programming. Any suggestions?
Update:
This is my eclipse.ini:
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.0.200.v20090519
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
-vmargs
-Xms40m
-Xmx256m
You can explicitely tell your eclipse session which jdk/jre you want it to start with adding the following in your eclipse.ini:
-vm
c:/your/jre/bin/javaw.exe
For more info on how to startup your eclipse refer here
I had a similar problem, with exception that Java was installed successfully.
Once I added c:/my-path-to-java/jre/bin to PATH (system environment variable), Eclipse started successfully.
Change the PATH environment variable from something like
...;%SystemRoot%\System32;...;C:\Program Files\Java\jdk1.7.0_17\bin;...
to something like
...;C:\Program Files\Java\jdk1.7.0_17\bin;...;%SystemRoot%\System32;...
Check your path variable from Computer's System Properties Environment Variables JAVA_HOME to ocorrect path to your jdk installation
Wonder if the Java install might be corrupt. Can you run the following on the Run prompt and paste what you get in code tags:
dir /d /s "%JAVA_HOME%" > "%HOMEPATH%\java2.txt" && notepad "%HOMEPATH%\java2.txt"
It makes sense that your PHP eclipse won't start either. Eclipse runs on java itself. Probably it cannot find the JRE.
so I see two possibilities:
The JRE is corrupt and you should reinstall it
Eclipse is getting confused by the 2 jre (unlikely to me) and you need to point it to the right one (as suggested by Dimistrisli).
I had the same issue. Eclipse (3.7) worked just fine for a while with JDK 6, and then I installed JRE 5 (please don't ask me why)
This eclipse wiki page, which seems up to date, states that:
If a JVM is installed in the eclipse/jre directory, Eclipse will use
it; otherwise the launcher will consult the eclipse.ini file and the
system path variable. Eclipse DOES NOT consult the JAVA_HOME
environment variable
And indeed, I did not change JAVA_HOME so that couldn't be it.
However, at the bottom of the same wiki page, someone added:
A comment on the JVM search order (on Windows) - My testing (Windows
7, Eclipse 3.4.1) shows that Eclipse also looks for a JVM in the
registry, in my case HKLM\Software\Wow6432Node\JavaSoft\Java Runtime
Environment
So I found the mentioned registry entry, which now had the value of "1.5" and changed it to "1.6", then restarted my PC (windows 7), and voila - Eclipse went back alive.
I agree that adding "-vm" might fix this, although it didn't seem to work for me (maybe I didn't add it in the right place/format). But IMO, the registry fix was the better one in my case. After restarting my computer and seeing Eclipse was back to normal, I uninstalled JRE 5 (through "Add or remove programs") just to tie up loose ends.
In my case installing the most recent JRE worked well: http://www.oracle.com/technetwork/java/javase/overview/index.html
I had the same problem when I recently installed JDK 7 Update 9. My eclipse did not open and when I run "java -version" from CMD, it did not work either.
I had PATH variable set to the correct bin directory.
Anyways, eventually when I set JAVA_HOME to the new installation directory, eclipse started fine. Not sure what is the problem with JDK 7 Update 9.
Make sure everything is setup correctly under "installed JREs" under the Eclipse preferences.
The simple solution that worked for me, since other resolution required admin privilege is executing the below command from command prompt
eclipse -vm C:\Java\jdk1.7.0_72\bin\javaw
Also, to make the eclipse shortcut work by editing the shortcut.Append -vm C:\Java\jdk1.7.0_72\bin\javaw in the target section
