Hi Michael G.,

I turned off the UAC and still had the same results. A friend let me borrow his TC Pro v14 to try, and it installed but failed to run as well. I think my version of Vista is just plain buggy :-) I've not had any problem with it until the IMSI software. As a test I downloaded the trial version of TC Pro v16 and it ran fine. Go figure?

Anyway, thanks for the advise.

Michael T.
