Sometimes (no idea why, seems random to me) the VDA update is stuck after prompted to reboot in the middle of the update like below.
VDA Update Stuck
After going through the logs (Get-content ”$env:LOCALAPPDATA\Temp\Citrix\XenDesktop Installer\XenDesktop Installation.log” -wait) I noticed that the VDA setup creates a RunOnce key just before the restart.
VDA Update Powershell Log
After checking the registry path ”HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce” there was indeed a key created with the name ”!XenDesktopSetup”.
VDA Update Stuck Registry
After deleting this key the update proceeded immediately.
VDA Update Proceed
I guess the registry key should delete it self after a reboot, but for whatever reason it doesn’t. This update was from 7.18 to 1808, but have happened to me in all different versions from 7.15 and later.
