Some legacy applications specifically require .NET Framework 3.5; newer .NET or .NET Framework 4.x is not automatically a substitute. Check your Windows version with winver first. Windows 11 through 25H2 offers 3.5 as an optional Windows component, while 26H1 (build 28000) and later use Microsoft's
