Deleting a folder

[Bungkai]

Simple question I know, I see

PHP Code:

 RMDir "$INSTDIR" 


being thrown around with or without the /r flag. I've placed a folder on the desktop and I was able to delete the files just fine. But I can't delete the directory. Also tried moving it with rename and whatnot but it doesn't seem to budge.

I set $INSTDIR as $DESKTOP/[folder name], and i checked to confirm it's the right directory with detailprint. But it won't budge. Need a bit of help with this issue.
