.NET 4 on Windows XP SP3

    Question

  • I have an application that requires .NET 2.0 but we install .Net 4 as it is the latest version.

    On a Windows 7 or Vista machine the program runs fine, but on a machine with XP SP3 when I try and run my application I get an error message telling me that the required .Net framework is not found. If I install .NET 3.5 everything works fine again.

    Why does .NET 4 work for .Net 2.0 programs in Vista and Windows 7 but not XP?

  • Hi Chris,

    Based on your description, you have some concern on ruuning your .NET 2.0 application on Vista (or Windows 7) or Windows XP.

    Firstly, we need to know some conception of .NET Framework.

    The .NET Framework has two main components: the common language runtime (CLR) and the .NET Framework class library. The common language runtime is the foundation of the .NET Framework.
    .NET Framework 3.5 uses CLR version 2.0 and so does .NET Framework 2.0 or 3.0, while .NET framework 4.0 uses v4.0.
    .NET Framework 3.5 includes .NET Framework 2.0 SP1 and 3.0 SP1 as prerequisite.
    Please read the following blog to understand the relationship between .NET 2.0, 3.0 and 3.5.
    See: http://www.danielmoth.com/Blog/2007/06/net-framework-35.html

    Secondly, we need to know more about the OS itself.

    Windows Vista (all editions) includes the .NET Framework 2.0 and 3.0 as OS components.
    Windows 7 (all editions) includes the .NET Framework 3.5 with SP1 as an OS component.

    This means you have the .NET Framework 2.0 as OS component if you have installed Windows Vista and Windows 7.

    Please see:


    For more information, here is a useful blog that shows what version of .NET Framework is included in what version of OS. See: http://blogs.msdn.com/astebner/archive/2007/03/14/mailbag-what-version-of-the-net-framework-is-included-in-what-version-of-the-os.aspx

    However, for Windows XP, .NET Framework 2.0 is not shipped as OS component.

    Thus, when you run your .NET 2.0 application on Windows Vista or Windows 7, it can be run properly. On Windows XP, you need to install .NET Framework 3.5 (.NET 2.0 is included) to support your application. Your concern could be related to .NET 2.0 instead of .NET 4.0.

    Hope this helps! If you have any concern, please feel free to let me know.
