When attempting to upgrade the Novell Client on Windows Vista systems, the installation stops with the attached error message:

"Installation Error: The Novell Client Installation is already running on this Windows machine. Please complete and close the existing Novell Client Installation program before attempting to run SETUP.EXE again.."

Prior to the install, the system was restarted, no instances of setup.exe. Monitoring task manager shows that ACU will attempt to start two instances of setup.exe.

We have multiple systems which yield the same error so it is not a 'one-of' situation.

If you run setupNW.exe, the client installs with no issues.

I can't see anyone else with this error - any suggestions? Thanks!
