MS VC++ Runtime Error when setting search path

Hi,
I thought perhaps my problem may have been related to anothertopic which states SW Explorer won't run and to that end, I updatedmy .NET 3 stuff. My error is not quite the same though - when I gointo the options and change my search path, the error pops up whenI try to apply the new search paths.

Please, if you've fixed the problem, would you help. Without theexplorer we cannot do a where used on non-vaulted parts - andthat's asking for trouble.
