PC Health Check says my system is Windows 11 compatiable, but Windows 11 install process backs out

[pcpalmhelp]

I have run PC Health Check app on my system, which declares my system as Windows 11 compatible. 

It is a older workstation, Xeon with Nvidia, pretty strong, but 5 years old. 

When I run Windows 11 install process, it works, but then backs out with a "uninstall changes" and I just end up back with my normal Windows 10. 

Is there a way to look at logs and find out why Windows 11 install decided to back out of my system?

If you don't have a lot of files and programs to reinstall, you can always try clean installing W11.

Sometimes the upgrades don't work for one reason or another and it would be difficult to pinpoint the problem.

I had two PCs that refused to upgrade to W11 from W10 and provided no errors or anything.

They got to around 87% and 'poof' back to the W10 desktop.  No warnings, no errors, no nothing.

I clean installed W11 on both of them a few of years ago and they have worked fine ever since and then they upgraded to the next builds that were released like one would expect.
