Invalid drive error ;-)

Actually, I don't think this is an InstallShield error, but a Windows Installer error. Anything differenet about the two machines? I've heard, that if My Documents or Documents and Settings folders are being hosted on a network (instead of the local HD) and the network is down, you can get this error.
I'd try a search on google to see if you can get any more pointers:
