.NET Framework 4.5 and Windows XP
You need to install the .NET Framework 4.5 to run an app or game on Windows XP.
The .NET Framework 4.5 and later .NET Framework versions are not supported on Windows XP.
If you need to run an app that requires the .NET Framework 4.5 or later, you will need to upgrade to a later version of Windows or find another machine that has a later version of Windows. You can also contact the publisher of the app, to see if they support Windows XP with another version of their app.
The .NET Framework 4 is supported on Windows XP, however, it will not run apps that require .NET Framework 4.5 or later versions.
You can contact Microsoft for help if you cannot get the correct version of the .NET Framework installed.
