Although I haven't read the full post here: http://www.bleepingcomputer.com/forums/t/130364/corrupted-addremove-programs/
it appears to be a similar problem to yours so it may be worth reading.
As usasma points out, this appears to be very much the same problem as in my post. Yours does not appear to be as severe because your applet was empty when you discovered the problem.
Before I go any further, I need to know your computer experience and your computer specs. If you do not feel confident poking around and making edits in the registry, this should not be attempted.
To make a short read of my post, I am still in the process of repairing the applet. I have other information to collect to complete my repair. Hopefully your information will be in better shape.
I will watch for your reply. OleGreyGhost
