UUP:
Download package created OK
.zip file expands OK
.ISO build runs to completion OK
.ISO mounts OK
However, when I run the 'setup.exe' file (as administrator) nothing happens.
This is probably an issue with UUP, so how do I report it to them?
Or iIs there anyone who can suggest a fix or...
Personally, I don't use / rely on 'Restore Points'; they are unreliable at best.
I suggest you use Macrium Reflect, AOMEI Backupper or Hasleo Backup Suite
From MR Support
The backups would be deleted based on if you have your retention rules to delete the backups based on "matching" or "all" sets.
You can find more information on that here:
