NetBeans IDE 7.2 does not start

Question

Previous to installing the latest version of the NetBeans IDE 7.2 I uninstalled my previous version. The ide does not start. I see the hour glass for a few seconds in my Windows Vista and disappears and nothing happens. I am left with no IDE to run. Your help is most appreciated. Rifai

Answer 1

What Bundle of Netbeans did you download?

• Download "OS independend ZIP" (at Platform) unzip and run it, does it work?
• Did you change something in config files (Netbeans 7.2/etc/)
• Take a look at NB Logfiles (<user>/AppData/Roaming/NetBeans/var/log) - any warnings / errors?
• Check if there are some settings left (<user>/AppData/Local/NetBeans and <user>/AppData/Roaming/NetBeans)? If yes delete them (backup if required)
• Is there any error message or dialog?

Edit:

Next thing you can try:

Go to your etc folder of Netbeans and open the file netbeans.conf (you need a better editor than notepad since the file has unix-linebreaks). Look for those two settings:

• netbeans_default_userdir="${DEFAULT_USERDIR_ROOT}/7.2"
• netbeans_default_cachedir="${DEFAULT_CACHEDIR_ROOT}/7.2"

Change both paths to something else like "${HOME}/userdir" / "${HOME}/cache" - but make shure you dont use one folder for both (see comments above the settings).

Now start Netbeans and check if both folders are created and contain some files. I guess with ${HOME} both are created in the bin.

Answer 2

This worked for me on windows 10 and Netbeans 7.2.1

Open Task Manager --> Go to Users Tab --> Look for Netbeans IDE, if found, select and then click on End Task.

Open Netbeans again, hopefully, will start.
