I ran into the same problem and found a solution. Make sure you download and install the latest "MS visual C++ redistrutable". My wifes PC has Windows 11 Home and when I tried installing TT to it, TT asked me to install MS C++, I did and it installed and activated perfectly. I then went to my PC that has Windows 11 Pro and installed the latest C++, it to then installed and activated without a problem. I tried everything I could think of and did all of TT's troubleshooting that did not work. For some reason MS doesn't download the latest C++ through Windows update, you need to go to MS and get it. TechPowerUp has an all in one install packeage that updates all the MS C++'s too. Hope this helps?
