Can not run any application built on .net

Over the weekend something happened to my .NET framework under Windows XP with Service Pack 3.
I was running 2.0 Framework with Service Pack 1, all of a sudden any .NET application I attempt to run fails with an 'Unhandled Exception'.

I have uninstalled all .NET frameworks and used the .NET Cleaner to fully remove.  I also then ran CCleaner to find any remains and removed those as well, with no success.  After installing 3.5 with SP1 same issue.

I tried to use a restore point from last week and all .NET Framework applications crash as they have no .net installed, then installing .NET leads back to the 'Unhandled Exception' errors.

I can't run the .NET Version Checker tool as it runs on .NET and crashes when I try.

Also followed these steps

Any other suggestions, or assistance would be great.
Thanks!

Only program that seems to work now is ATI Catalyst, after completely removing .net and trying again.  Any other program just crashes out with unhandled exception.

Can you send a screenshot? Also, is there anything related to your problem in your event viewer?

I will post a screenshot, in the event viewer;
I get Event ID 1013
Source MsiInstaller

Description:
Product Microsoft .NET framework 2.0 Service Pack 2 - Microsft ..
that is probably due to me trying to uninstall through add/remove

The other one is
Evenit ID: 5000
Source .NET Runtime 2.0 Environment

That leads to this:
M911816

Which doesn't resolve.
I found a tool that tells me the .net version and currently says no .NET is installed, but when I do install and try to run an application it crashes.

Screenshot soon.

if this is the case then how can a .net application run
try repairing your operating system, that might help

Hmm, maybe try "Method D: Reset permissions for any unwriteable registry subkeys" from http://support.microsoft.com/kb/917925
