Failed to uninstall Netbeans 7.2

Hi,
I have been using Netbeans 7.2 recently but decided to uninstall it, when I do however I get the following message.

NetBeans IDE Installer
Critical Error
An unexpected exception happened in thread Thread-7
Exception:
Java.lang.NullPointerException:
Null
You can get more details about the issue inthe installer log file:
C:Documents and SettingsAdministrator.nbilog20120602142147.log
When I click "OK", there is a different error in the git repository.

NetBeans IDE Installer
An error occurred while running java process
Fatal: Not a git repository (or any of the parent directories): .git
Anybody else have any similar experiences?
