I'm running Citrix 4.5 on Windows 2003.
I have made a little headway I think, still testing though.
It seems if you add the Trueview user to the local admin group of the server it works. I have done it with one test account and now working on another.
Are you using TrueView 2012?
I haven't tried it with this version but I have it working using 2009 without needing to add the users to the local admin group.
Let me know how you get on.
