Trouble using FSrealWX on Windows 11

When I had Windows 10, FSrealWX worked great. 
But now I am on Windows 11 and I am having problems getting it to work.
First of all I downloaded a new app. Then I had to activate it as administrator, but when I finally opened the app, I received lots of errors.
I registered using my old FSrealWX FSUIPC and WideFS keys, but I still received many errors.

Can someone help please?
