You attempt to uninstall Citrix XenApp 6.5 from one of your servers but it fails with the following error message:
Operation could not be completed (error 0x00000705). Windows cannot locate a suitable printer driver. Contact your administrator for help locating and installing a suitable driver.
This error really got me thinking and trying to figure out why something related to a printer would stop me from uninstalling XenApp 6.5 on a Windows 2008 R2 server. The first thing I tried was to remove all of the printers in the Devices and Printers console but that didn’t work. I then followed by uninstalling various applications that was published by XenApp 6.5 (note that this XenApp server already had all the applications it published removed from the AppCenter) but that didn’t work either. As I began running out of ideas, I stared at the Programs and Features window and noticed 2 hotfixes I installed for this XenApp 6.5 server:
Citrix Hotfix XA650W2K8R2X64011
Citrix Hotfix XA650W2K8R2X64001
Since I had nothing to lose, I went ahead and uninstalled those 2 hotfixes and long behold I was able to uninstall XenApp 6.5 without any errors. Strange but I’m glad I managed to uninstall it with Programs and Features even though the uninstall didn’t remove the node from the farm (I had to manually remove it).
