A question came up the other day as we were installing Xenapp 5 (x64) on several Server 2008 (x64) hosts.  How can you determine if the 64 bit version of XenApp 5.0 is actually installed?

• The first oddity we noticed was that XTE.exe was not running under a 64 bit process.
  • 
• In fact, what alto got OS was the fact that the following were also running under *32 bit processes:
  • ctxxmlss.exe *32 – Citrix XenApp XML Service
  • RadeObj.exe *32 – Citrix XenApp Plugin for streamed Apps Session COM Server
  • RadeSvc.exe *32 – Citrix Streaming Client Service
  • XTE.exe *32 – Citrix Gateway Core Service
  • CdfSvc.exe *32 – Citrix Diagnostic Facility COM Server
  • pnamain.exe *32 – Citrix Applications (program neighborhood)
  • and ultimately, even ImaSrv.exe *32 was also running as a 32 bit process.
  • 

After viewing the above, one would be definitely inclined to think something odd is going on. XenApp must be running in 32 bit mode. Apparently this is not the case. Even though the XenApp 64bit gets installed to the X86 directory and several XenApp relevant processes run in task manager with the appended “*32″ next to the service name.

• Even via the registry, you can confirm the existance of 32 bit apps by looking at the following registry keys. Note: true 64 bit applications would be installed to HKEY_LOCAL_MACHINE\SOFTWARE.
