I'm away from the PC now. But when I click on the Insider Program panel it resets the regedit and shows that I'm out
If you are out and not in any insider channel I think this will fail.
Need to be on insider R.P. to get to the screen I showed.
Maybe you can try while offline and disconnected from the network, but I'm afraid it may still fail with this message if it is not on insider R.P. or Dev.
Doesn't hurt trying...
Try renaming the file in installation media sources directory:
Rename from appraiserres.dll to appraiserress.dll.bak and then run setup and see what happens.
If that does not work you have to clean install either Win 10 or Win 11 22454.1000 using some other tricks.
