Active Directory Users and Computers Error: “the application has requested the runtime to terminate it in an unusual way”

UPDATE [6/19/2009]:  Below is my original fix for this problem however in the comments section frymaster provided an alternative.  I am no longer running Vista 64 so haven’t tested it but another user has confirmed it worked for him.

Try deleting this file:

%userprofile%\appdata\Roaming\Microsoft\MMC\dsa

It will be recreated after you shut down your MMC console.

Thanks to frymaster for the update!

I installed the newest version of RSAT for Vista Service Pack 1.  I am running the 64-bit Version of Vista.

After installing this newest version I got this error when trying to start Active Directory Users and Computers:

Microsoft Visual C++ Runtime Library
“the application has requested the runtime to terminate it in an unusual way”
