Offline Installation gets to choose what files to keep, and the only radial button I get is "Nothing". I'm really trying not to totally wipe my slate in this process, but I am not sure what options I am left with.

I believe I have supplied all troubleshooting steps I have taken (some of which with the assistance of Chat Support). I'll update this top post if there are any steps I missed or suggestions attempted.

@SacrifusionDid you get anywhere? Same issue occured for me. No matter what 'solutiond' I tried, the error keeps on coming.

[#3]

Nope. Since today was release day, I tried my whole battery of tricks again to see if there'd be any difference, but none at all.

I even manually deleted the updated download files.

Not even sure why I'm trying so hard. Win10 is working great for what I need and the odds something I need malfunctioning on 11 will probably out balance any benefits of a shiny new OS.

[#4 · Accepted solution]

@SacrifusionValid point about Windows 10.Good for another 4 years I believe.

I discovered why mine wouldn't install. The SSD has 2 partitions - one for Windows and the other for Data. Looking at the Registry I saw that the Data partition (D:\ProgramFilesDir) was set as default installation directory. Changed the relevant entries back to C:\ProgramFilesDir, and Bingo! Now in possession of Windows 11 in all its dubious glory!

Ah, I'm sure that's my problem too. I've got my data on my micro SD for D:\ProgramFiles.
Shame no experts chimed in to point this out too us sooner.
Thanks for your legwork!

Can't find the site where I found the answer, but this one ( https://gearupwindows.com/how-to-change-the-installation-path-from-c-to-another-drive-in-windows-11/ ) gives you similar information, should you want to pursue the issue. Don't forget to change it back when installed, and BACKUP the registry before you start!

I'm 99% sure this fixed it for me too. Still in progress of installing, but I had also switched to D:\ProgramFilesDir, so I think this was also my problem. This was a nice catch! Thank you so much for sharing. Took me hours to find an answer that works.
