Netbeans 7.1 won't run after installing python

Question

I have just installed python in nb7.1 using http://deadlock.netbeans.org/hudson/job/nbms-and-javadoc/lastStableBuild/artifact/nbbuild/nbms/updates.xml.gz and and it doesn't show up.

I want to turn some plug-ins of from its home dir. How can I achieve this?

then I read on NB Forums (http://forums.netbeans.org/post-124523.html#115641), I found this guys saying "Dont do this step it will crash Netbeans" But no one is telling how to reverse this.

EDIT

here is the log output

I found the blasted plugin under Users\$MyUser$\AppData\Roaming\Netbeans\7.2

Made special note of (read: deleted) files in Python-sounding directories that matched the time I ran into the startup problem. Netbeans ran fine afterwards.

At least in my case it was the addition of the "development update center" which broke netbeans and not the python plugin itself. See post https://stackoverflow.com/a/9993301/970910 for a possible fix the issue.

In order to remove the plugin manually :

Go in your home, there is a .netbeans directory. Go inside and delete the plugins files here.

I don't think its a good idea because i have my version control installed there. and I don't want to mess with my local history etc. Can you please suggest something less destructive? – Junaid Qadir Shekhanzai Mar 04 '12 at 14:01
You can just delete the directory that contains the plugin python and not the whole directory. – alain.janinm Mar 04 '12 at 14:05
Ok, I just moved the .netbeans folder and started netbeans but it didn't show up? – Junaid Qadir Shekhanzai Mar 04 '12 at 15:46
You need the directory I think, delete everything inside is a bad idea. Can you identify where files specific to python plugin are and delete only those? – alain.janinm Mar 04 '12 at 15:48
Please check the log contents, can you figure out what does it mean? regards – Junaid Qadir Shekhanzai Mar 04 '12 at 17:03
You seems to have delete too much files. I don't know exactly what are the python plugin files... you have to find out and drop only those. Sorry can't help more. – alain.janinm Mar 04 '12 at 17:53

Overwrite your netbeans with a new install, better upgrade your netbeans(latest version) with a fresh install, keeping old one there. Then uninstall your old copy it will keep your project untouched.

If you want to keep netbeans7.1 then just overwrite and then remove the plugin using netbeans builtin plugin manager.
