The editor and engine have been tested and confirmed to work on all major releases of windows from vista to 11.
Your post is a little vague, what isn't working about it?
If the editor isn't starting, you may need to install .net framework 4.6 or newer: https://dotnet.microsoft.com/en-us/download/dotnet-framework/net46
If games aren't launching, you might need to install visual C++ 2019 or later: https://aka.ms/vs/16/release/vc_redist.x86.exe

If the problem is something else, let me know
