Upgrade Fences 4 -> Fences 6 Windows Black Screen
Fences Parallels W10 on iMac
I have upgraded Fences 4 to Fences 6 for a W10 installation that runs under Parallels on an iMac. I didn't want to loose my Fences 4. That's why I installed Fences 6 over Fences 4 without deinstallation. The update process showed no problems. After restarting W10 as the last step of installation W10 shoot down but did not resume properly. There was only a black screen without any function or login window. Fortunately I had a Parallels snapshot available and I set W10 back to this snapshot and I received back the state with Fences 4 installed. I have no idea of the reason of this problem.
Fences 6 (multi device license) upgrade process from Fences 4 (multi device):
1. check upgrade elegibility -> yes
2. download updater of Fences 6
3. installation of Fences 6 with running Fences 4 in the proposed standard directory (is this wrong?)
