Does Citrix XenApp working on Windows 7 64 Bit?

Question

I've been trying to get the Citrix XenApp client going - but as soon as it connects it crashes on Windows 7 64bit. Citrix support has 0 information on Windows 7, so I'm curious if others have gotten it to work, of it's just me.

thx.

Answer 1

Found a workaround.

It has something to do with the version of Citrix that we're using on the server vs. the latest client version.

The workaround is rather simple, in Windows 7 you need to associate the ".ica" extension with C:\Program Files (x86)\Citrix\ICA Client\wfica32.exe program.

Answer 2

There's a hotfix for this, it has to do with the size of the Terminal Server public key, see Citrix ICA clients may crash when they are connecting to a Windows Server 2008-based terminal server that has Citrix Presentation Server installed
