Several common pieces of software I try to install while logged on as a user (the user is a local administrator) on a new windows 7 64 bit pro PC ends with an error that says bad drive h:\. The h:\ drive is a network drive where i have moved the user's my documents folder. If I log on as the domain or local admin, the software installs fine. I have had this happen on three different HP Windows 7 PC's. Any ideas?
