After having tried for a long time to fix a number of problems (see Not Running Genuine Windows Error 0x8004fe21
for the details), I've tried to do a repair install.
This fails however during the "compatibility check" with the following error message:
"The following issues are preventing Windows from upgrading. Cancel the upgrade, complete each task, and then restart the upgrade to continue.
An error prevented a required compliance check from completing. Cancel the installation and try upgrading again."
Does anyone understand what this error message means and how to solve the problem?
