How do I tell what version of Citrix is installed on a server? 32-bit or 64-bit?, in the x64 Terminal Server / Citrix forum on BrianMadden.com

I just started a new job recently and need to know which version of Citrix is installed on our servers. I know it is Citrix Presentation Server 4.5 Enterprise, but I don't know if Citrix is 32-bit or 64-bit. The server is running Windows 2003 Enterprise x64 (not R2 version). I thought this would be easy to figure out, but evidently its not.

Please help!

The easiest way to check would be to check where it is installed to. 32 bit applications are installed by default in the Program Files (x86) directory, where 64 bit apps are just installed under Program Files. That would be the easiest way.

Easy! Citrix Presentation Server 32 bit is not supported on x64 servers and will not install.

Also to check for a 32bit program, you could load task manager and if the e.g. ImaSrv.exe has *32 against it. it is 32bit

Even the x64 version of XenApp server is still 32-bit, so checking for a 32-bit executable won't help.

Youe right lots of the code in the 64bit version of XenApp is still 32bit, but credit to Citrix they did re-write the IMASvr.exe (v4.5)

I can see how they could get away with some modules of Citrix being 32 bit, but the drivers like wdica.sys would have to be 64 bit.

That's the main difference between the 32 and 64-bit versions - Citrix had to re-write (ie re-compile) the drivers as you can't run 32-bit drivers under x64, but most of the other components (apart from IMA as stated above) remain 32-bit
