I have a client that needs to install Citrix XenApp 6.5 on a server 2008 32bit, non-r2 VM. When attempting the install, it states I need .Net 3.5, but crashes after the install attempt. 

I attempt a windows update figuring that will work, but even though I have not run any updates on this VM, it states they are up to date. Can't even load IE 9 onto it without the install crashing. 

Wondering if dealing with win 2008 32bit non-r2 is THAT difficult to work with? Any suggestions on getting XenApp 6.5 on it is appreciated.
