Hi Ramesh
Thanks for being there again.
I did the three steps suggested. There was already a c:\drivers directory, I renamed it to drivers-old to create a clean one. So still have that one.
The three steps worked out well.
Driver uninstalled
Then, I rebooted before I launched Setup again as admin, not sure if that was correct or not (would the driver be reinstalled again during boot?)
It did not start the real install process but stopped in phase getting thing ready to install. (the window just closed without any notification)
So I repeated the three steps, and now launched the setup as admin, without first doing a reboot.
Same situation, it does not get along Getting thins ready, the screen just closes, like before, without starting the install.
I saved the Panther directory, and uploaded it again, with current date. There is no Rollback (probably, because the install did not get started, only preparing.... (Panther zip with today's date)

Knowing that before deleting/renaming the Appraisseres.dll, at least let the system started the install, I tried that too, so I renamed the dll. and launched the setup, (still without reboot, so with uninstalled driver). Now the setup process, hangs at stage "getting things ready for you to install, after long time I killed the windows, resulting in setup is cleaning up for you, however this is also hanging now. not sure if I can just kill that process/Window.
I checked the Windows.-BT sources directory, and noted that my appraisserres.dllold disappeared and there is a appraisserres.dll again. (with old date).
I did not want to kill that cleaning up window, so that still hangs, can I kill that one?
So after we started uninstalling that driver the install process does not start at all, only setting up (before the bluescreen comes with installing Windows 11. and the cleaning up process of the setup is hanging
