Clean Installation of .NET Frameworks RRS feed

  • Question

  • For several months, Auto Updates has been unable to install something and the only message I get has to do with .NET FRAMEWORKS 1.1 service pack1.  Here is the whole thing: Microsoft .NET Framework 1.1 Service Pack 1 Security Update for Windows 2000, Windows XP, Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 (KB953297)

    Note that according to the Add/Remove Program control panel item, my XP home system was already up to .NET Frameworks 3.5. I wanted to do a clean install but the only things that would uninstall were the most recent programs (3.5 and 3.0 sp1(I think)). Still showing as installed are:
    3.0, 2.0 sp2, 2.0 SDK-ENU, 1.1 Hotfix (KB928366), and 1.1.

    Now I get setup errors as I try to uninstall to older versions of .NET Frameworks.

    No prerelease versions have ever been installed as far as I know.

    Where do I go from here?

  • Hello,

    The .NET Framework 3.5 is an add-on that requires the .NET Framework 2.0 SP1 and the .NET Framework 3.0 SP1 to be present as prerequisites.  If you have the .NET Framework 3.5 installed, you will not be allowed to uninstall the .NET Framework 3.0 SP1 or 2.0 SP1 until you first uninstall the .NET Framework 3.5.  You will also not be allowed to uninstall the .NET Framework 2.0 SP1 until you first uninstall the .NET Framework 3.5 and the .NET Framework 3.0 SP1.

    In addition, the .NET Framework versions 1.1, and 2.0 are completely separate from each other, and one version can be present on a computer regardless of whether the other versions are present. When versions 1.1 and 2.0 are on the same computer, each version has its own common language runtime, class libraries, compiler, and so forth. As a result you could here uninstall 1.1.
