Installation prerequisites

The download site says that PrePoMax is based on the Microsoft.NET Framework 4.8, and that it must be installed on the computer for PrePoMax to work. My operating system is Windows 11 with Microsoft.NET Runtime 6.0.20, would anyone know if PrePoMax would work with Microsoft.NET Runtime 6.0.20?

It should work on Windows 11. The Microsoft is terrible at naming its products and Microsoft.NET Framework is completely other product than Microsoft.NET Runtime. You don’t need to install PrePoMax so it is easy to try.
