SysCmd is access vba not vbscript. Take a look here www.tek-tips.com/viewthread.cfm?qid=1088751
for tips on how to get the access version. But are you sure that you can assume the Access came with MSOffice? I have Office XP (2002) without Access, and I also have Access 97 so if you used that method on my setup you would be assuming I have Office 97!
Here's a way to get the Word version
you can probably do the same for Excel using it's Application object.
