NetBeans IDE 7.2 not starting

Before installing the latest version of NetBeans IDE 7.2, I uninstalled my previous version. The idea does not begin. I see the watch glass for a few seconds in my Windows Vista and it disappears and nothing happens. I have no IDE left to run. Your help is greatly appreciated. Reef

What Netbeans package did you download?

  • Download the "Independent ZIP archive" (on the platform), unzip and run it, does it work?
  • You have changed something in the configuration files ( Netbeans 7.2/etc/ )
  • Take a look at NB Logfiles ( <user>/AppData/Roaming/NetBeans/var/log ) - any warnings / errors?
  • Check if there are any settings ( <user>/AppData/Local/NetBeans and <user>/AppData/Roaming/NetBeans )? If yes, delete them (backup if necessary)
  • Is there an error message or dialogue?

Edit:

The next thing you can try:

Go to the Netbeans etc folder and open the netbeans.conf file (you need a better editor than notepad, as the file has unix-linebreaks). Find these two settings:

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

Change both paths to something else, for example "${HOME}/userdir" / "${HOME}/cache" , but make sure that you do not use the same folder for both (see comments above settings).

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