I just installed the newest version of .NET. Now when I go to the Administrative Tools and double click on the Microsoft .NET Framework 1.1 Configuration option, it comes up with this message:

Snap-in failed to initialize.
Name:.NET Framework 1.1 Configuration
CLSID:{some guid}

Also if I try to open the Microsoft .NET Framework 1.1 Wizards option, it comes up with this message:

ConfigWizards.exe - Common Language Runtime Debugging Services
Application has generated an exception that could not be handled.
Process id=0xcf4 (3316), Thread id=0x6dc (1756).
Click OK to terminate the application.
Click Cancel to debug the application.

If I hit Cancel I get this:

ConfigWizards.exe - No debugger found.
Registered JIT debugger is not available. An attempt to launch a JIT debugger with the following command resulted in an error code of 0x2(2). Please check computer settings.
cordbg.exe !a 0xcf4

I get almost exactly the same thing when I try to open Web Matrix.

If have unintalled and reinstalled .NET several times, making sure that my antivirus software was turned off. Anybody have any clue what is going on here?
