Netbeans 7.2 not starting

I was having the same problem .... with netbeans 7.2 ,go to user/appdata/roaming/7.2/modules/ and delete all the jar files except docs,ext,locale folders ... and start the ide again... basically the problem betides when u update the ide after update when u start the ide it stuck to the loading module phase.

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.
