Sorry to dig this old thread up, but I purchased a new laptop today which of course has Windows 11. I had to try installing and running Control:PC since I believed that Win 11 was just a fancy wrapper for Win 10. I can confirm now that Control:PC does run on Windows 11. It installed the exact same way as it did on Win 10. I ran the Control:PC install file and it complained that it needed .NET Framework. I downloaded .NET Framework 3.5 SP1 (Runtime) from Microsoft and installed it. I reran the Control:PC install again and it installed. I had it run Control:PC after installation and as the program was coming up, it prompted me to allow three of Control:PC's components access through my firewall. After that was done it had found my server and the music was playing.

This was the link I used to download the .NET Framework file: https://dotnet.microsoft.com/en-us/download/dotnet-framework
