I'm trying to install the GroupWise 6.5 SP3 client on my Win2K3 PS4 server. I'm having an issue where after clicking the .exe for the install, the server just sits there. Nothing happens. I've researched this and have only come up with Windows DEP and Citrix Virtual Memory Optimization. Both of which we are not using, so I've eliminated those. I did test installing GW client on a pure TS server with no MetaFrame/PS installed and the install ran just fine. So it seems to be Citrix that is getting in the way. Any ideas or other experiences with this?
