Office2K Auto Intall Error “Installation

ON an NT network we are upgrading to Office 2000 from Office 97 using the MS auto install on WIN 95 clients. It works great except in a few cases where about 10-20% into the install I get the error “Installation terminated prematurely.” I’ve uninstalled Office 97 and deleted registry entries but still no effect. I tried a manual install from CD-no effect.
