I was having the following issue when opening MSFS2020_AutoFPS
But when I clicked "Yes" nothing happened.
Using Google I found the .NET Desktop Runtime Download page.
https://dotnet.microsoft.com/en-us/download/dotnet/7.0
I downloaded the installer and Installed.
After that MSFS2020_AutoFPS opened correctly
Some users are having to download and install .NET 7 manually like you have. I will add an entry to the readme to cover this possibility. Thanks for letting me know.
