I did an upgrade from XP to Vista (just doing r&d) with the Novell Client 4.91sp3 still installed, as well as Zenworks Agent for Zenworks 7 sp1. I was able to uninstall the agent after the upgrade to Vista but cannot uninstall the Novell client or the NICI. If I try to install the Novell Client for Vista (thinking it would detect the 4.91sp3 client and remove it), I get a blue screen after rebooting. Has anyone else experienced this and do you have any ideas?
