I have tried to uninstall Netbeans from control panel, but when I try to remove it, this pops out "JDK not found on your computer" https://imgur.com/a/KQfrG , but Netbeans is working perfectly, my JAVA_HOME and Path have the right paths. I tried to launch the installer, maybe it would change the "uninstall.exe", but it didn't do anything. When I execute uninstall.exe, it doesn't create a log file in .nbi/log, I have there just the installation and logs for the times I tried to reinstall in hope for "repair"

I am using Eclipse Juno on windows 10 machine, It was working fine till now, I performed Disk Cleanup for C drive (Deleting all System logs, temporary files.. etc ) after Restarting the System ,I was not able to open Eclipse. after clicking on eclipse icon the screen appears and disappears soon.
Earlier also i have performed such Disk Cleanup activity but never faced such problem.
Please Help me in fixing the problem.
Try to run Eclipse in clean mode.
Right click on the Eclipse Juno execution icon on the desktop/folder, go to properties and add -clean to the end of the Target path.
For example:
C:\eclipse-juno\eclipse.exe -clean.
After a successful (and slow) launch, remove the -clean from the path.
It could be a configuration issue in Eclipse.
Open eclipse.ini, try to increase the memory:
-Xms256m
-Xmx1024m
In Netbeans IDE 8.2, I click in "New Project" and no window shows up.
The same happens when I click in "New File" (But I guess it is because there is no project open).
What could it be?
I installed Netbeans downloading .sh from the official website and running sudo chmod +x <netbeans.sh>.
I use Ubuntu 14.04.
I encounted the same problem when I installed Netbeans 8.2 in Linux Mint 18.
From Netbeans log View > IDE, it reported this error which appears to be a known problem (Bug 258945 - ClassNotFoundException: javax.activation.DataContentHandlerFactory). I noticed the keyword specified for this issue is JDK_9.
SEVERE [global]
java.lang.ClassNotFoundException: javax.activation.DataContentHandlerFactory
at jdk.internal.loader.BuiltinClassLoader.loadClass(java.base#9-ea/BuiltinClassLoader.java:366)
I went in and changed netbeans_jdkhome entry in /usr/local/netbeans-8.2/etc/netbeans.conf from java-9-oracle to java-8-oracle
netbeans_jdkhome="/usr/lib/jvm/java-8-oracle"
This fixed it for me.
Appending
-J--add-modules=java.se.ee
to netbeans_default_options within etc/netbeans.conf fixes the issue.
I saw a solution to this problem in another thread. I was having the same problem as you. The problem you mention is with Ubuntu, but it will work for Windows as well.
The problem is just that the JDK is not compatible with the netbeans (I used version 9). It works once you reinstall Netbeans and use an older version of JDK (I use version 8).
I have installed Windows 10 Enterprise (64 bit). I have also successfully installed the Java Runtime Environment (v9.Build.83.x64).
The problem is, I cannot install any version of Matlab on the PC. I have tried to install different versions. Each one of the installations became stuck when I clicked on setup of Matlab. The installation does not run Java programs and only its icon in the taskbar is shown, but would not run. This also causes the PC to freeze and makes me run task manager and end task setup of Matlab. I did an install and uninstall java but that does not help either.
What could be wrong?
First, make sure that you right-click the Matlab installer file “setup.exe” and select "Run as administrator". If the installer auto-launches from the dvd, cancel the installation, then from the Start menu open “Computer”, then right click on the dvd icon and select “Open in new window” or “Open with file explorer”, the right click on the file “setup.exe” and select "Run as administrator".
Second, the Java Run time Environment may not be the same as full Java. To be sure, go to http://www.java.com/en/download/win10.jsp and download and install java. Windows 10’s Edge does not use java and will fight you a bit on some of the java installation sites.
Third, an old version of matlab (version 7, R14) installed for me on Windows 10, but kept crashing when I started matlab, creating a long dialog with java error references. There are two ways to fix this.
A) As shown in the site:
http://www.vidnis.com/2013/03/how-to-use-matlab-7-in-windows-8-and.html
1) Go to the folder \sys\java\jre\win32. You will find a folder with a name similar to jre1.4.2 or jre1.5.0_07.
2) Open a new window and go to the folder C:\Program Files\Java. You will find a folder named jre1.8.0_91, or a similar version which does not match the Java version in the Matlab folder opened in step #1.
3) Copy (not Move) the entire folder from the folder C:\Program Files\Java to the Matlab folder opened in step #1. You can leave the old Java folder in the Matlab folder or delete it, it doesn’t matter.
4) In the Matlab folder opened in step #1, there is also a file named jre.cfg. Open it with the Notepad text editor, then change the old java version number (such as 1.4.2) to the new Java version (such as 1.8.0_91). Save the jre.cfg file and quit Notepad.
5) Now launch MATLAB, hopefully it works.
B) I also got matlab to run by right-clicking on the matlab.exe icon (or a shortcut icon) in directory MATLAB7\bin\win32, select “Properties”, select the tab “Compatibility”, then under “Compatibility Mode” click the checkbox “Run this program in compatibility mode for” and select “Windows Vista (Service Pack 2)” or any Vista. None of the other options of Widows compatibility worked for me.
Good luck.
I have a mac running os x 10.9.4 and I downloaded the newest version of eclipse. It downloaded fine and installed but whenever I try to open it, I get an error that says, "Version 1.6.0_65 of the JVM is not suitable for this product." I downloaded and installed Java 7 and tried opening eclipse again only to get the same error. Anybody know how to fix this? Thanks
Make sure you have the JDK installed. Google will point you to the runtime engine (JRE) if you search for a Java download (probably called jre-7u67-macosx-x64). Click on "show all Java downloads" in the download page and look for a link "looking for the JDK?" on the left . As of today, the JDK can be found here and should have a name like jdk-7u67-macosx-x64 or jdk-8u20-macosx-x64. Both should be fine for a recent Eclipse Luna install.
If you want to run Eclipse Luna with Java 1.6, you can change the entry in the .ini file. Open the Eclipse application bundle by control-clicking and select "show contents". You will open a new finder window with a single folder "Contents". Open it, then open the folder "MacOS" and edit the file eclipse.ini which you will find inside. Change the line -Dosgi.requiredJavaVersion=1.7 to -Dosgi.requiredJavaVersion=1.6. Close and save, and now Eclipse will run in a minimum configuration. But you really want to install the 1.7 JDK.
For those using Mac OS X Mountain Lion (10.8)+. When you launch Eclipse for the first time, you may see the message "Eclipse can't be opened because it is from an unidentified developer."
To launch Eclipse for the first time, press the control key, click on the Eclipse icon, and select Open.
