During a recent XenApp 7.5 / PVS 7.1 implementation we had to upgrade the PVS Target device software.
After the reverse imaging/upgrade/imaging of the vdisk, we ran into the following issue. When starting an ICA session, the session was showing up in Taskmanager, but the Receiver showed a persisting black screen.
Using CTX126869, we had a look at the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows\ AppInit_DLLs registry value:
mklink /J “C:\PROGRA~1” “C:\Program Files”
mklink /J “C:\PROGRA~2” “C:\Program Files (x86)”
After the recreation of the links, the launch of the ICA session succeeded.
