Yup, which is why I'd use the WMIInstalledProducts (or similar WMI calls) to get a list of apps, then search for the Microsoft Office product, then check the "bitness" flag. Does all the work to detect the product, version, and bitness.

Of course, this has been a discussion about general methods, with little work done to create an all-encompassing process. So - are you up to writing this and posting a UDF, Brad?? \:D
