.NET Framework 4 Installation fails with 0x80070643

    Question

  • Some updates were released this week and a couple of those were for .NET Framework and they wouldn't install with error 0x643. I ran the fixit and then I followed method 2 on this page:

    http://support.micro....com/kb/923100/

    This removed .NET Framework 4 and reset 3.5 so I had to install some updates for 3.5 which worked fine. However when I try to reinstall .NET Framework 4 again the installation rolls back, here is some information from the logs:
