.NET Framework 4.7.1 is from 2017, the current .NET Framework is "4.8" which most people have to run current games and other things.
The issue is those of us with "Current" .NET Framework can't downgrade to an older version, nor play the game as is, as you can see below.
why did you decide that it depends on the .net version? Judging by your description of the problem, you installed the game in a folder that requires administrator rights to access.
the solution to your problem is to install the game in a private folder, for example, in d: / games or run it with administrator rights.
Well, i did not do either of those things, additionally I came to that conclusion because the game specifically requires 4.7.1.
Ya know, the more you reply to what I'm posting, the sketchier this whole thing is starting to feel. From the Nature of how the game gets installed and boots up, to the other additional steps.
I've posted what I needed to post, good luck.
