Netbeans 7.2 not starting

Question

I recently installed Netbeans 7.2 beta and it worked fine. Then I installed Netbeans 7.2 final release on top of beta and during the installation, Netbeans 7.1 and Netbeans 7.12 were there. Now when I launch Netbeans, it does not go beyond "loading modules" stage. Simply the Netbeans screen disappear few seconds after the launch. Then I did the following.

• Uninstalled all the Netbeans versions and re-installed Netbeans 7.2
• Deleted AppData/Netbeans folder
• Deleted User/.nbi folder
• Searched the registry and deleted Netbeans related entries. (But only one entry was found)
• Deleted Netbeans Folder in Program Files folder.
• Uninstalled and Re-installed in a separate drive.
• Uninstalled and Re-installed under another user account.

None of the above worked, the only thing I did not try was to re-install the Windows XP operating system.

It there any option to try before re-installing the operating system?

+1 Nice! this happened with me in ubuntu & windows both, several times but no fix worked as this one did. – Tharp

This solution worked, but it seems like I need to reinstall all my plugins? – Siusan

I can't see modules directory under C:\Users[username]\AppData\Roaming\NetBeans\7.2, but config and var :( – Drye

got the same issue with NB 8.1 ... your solution just saved me :) – Rockling

@Miron, did you manage to sort the issue out? I'm on Netbeans 7.3 and as your case, I can just see config and var under that directory, there's no modules folder – Ladylike

Answer 2

First of all, you need to check proper version of JDK is installed. Netbeans 7.2 requires JDK 1.7, not 1.8.
You can check {Netbeans Install Path}/etc/netbeans.conf. There find netbeans_jdkhome and its value. Make sure you install JDK1.7 and this line netbeans_jdkhome="C:\Program Files\Java\jdk1.7.0_25" for example.
If not, change the value to proper installation path.

Answer 3

That's some stability issue with NetBeans 7.2

Just Kill and Restart the IDE and it should be fine.

Answer 4

Make sure that right JDK directory chosen in the installation wizard if you not sure you can change it from C:\Program Files\NetBeans {netbeans version}\etc you will see a file which is netbeans.conf edit it(I am using Notepad++ for that) At the bottom of the file, you will see a line netbeans_jdkhome="C:\Program Files\Java\{jdk directory you want}" make sure it is valid JDK and it is JDK, not JRE

Answer 5

I had the same problem, make sure you have the required JDK version configured during the installation process.

Answer 6

First tried everything to no avail, finally I had to uninstall NetBeans 7, then install NetBeans 8, which also aligned with my JDK 8. This resolved the issue for me. Hope this helps others.

Answer 7

Ah, finally this worked with me on version 11.3, delete this folder, then run the program again

Answer 8

I found out in my Windows installation of Apache Netbeans 12.4, the file 'tctracker.properties' in 'C:\Users\user\AppData\Roaming\NetBeans\12.4\config\Preferences\org\netbeans\core\windows' was filled with null values. I fixed the issue with letting netbeans generate a new file by moving this '12.4' directory to somewhere else on the disk, starting Netbeans, letting it generate a new 'tctracker.properties'-file, stop it, replace the corrupt file in with this newly generated file and put the '12.4' directory back in place.
