@radar,
This Forum seems pretty dead to me. I would not expect any replies from the new owners of Tweaking.com.
If your computer is Windows 11, or a Windows 10 with all of the updates, it appears that the "REPAIR" program is not being maintained.
If that is so, it is dangerous to run it on those two versions of Windows. Every monthly Windows Update changes Windows, and a repair program that is not being constantly updated is bound to fail at some point in time.
I would recommend ceasing to use the product. I had a licensed version that I ceased using years ago when Shane CROFT, the developer, left the company, to start his own company.
I hope I am surprised, and you get a reply from the new owners. I visit here daily, and have never seen anyone reply to users. As you can see, the Forum is pretty locked down, except for spam, which is cleaned about monthly.
Have a great day.
Regards,
Phil
