The upgrades were installed from a workstation running XP. The upgrades were for Lanpak, OE, BR, SA,AP,AL, AR and IC. All upgrades were tested and access confirmed. We have no problems with the XP machines. What is puzzling is that the other upgrades run fine on the Vista machines with no error. All report tables are in the same drive.

I will try disabling User Control and try the installation again and also run the Chksys.
