Microsoft .NET Framework installation/removal problems. RRS feed

  • Question

  • I have a problem with installing Microsoft .NET Framework 2.0.

    I am running Vista SP2, so .NET Framework is integrated into the OS. After trying to run an application, I got the 0xc0000135 error.

    I read on some fora that this could be solved by reinstalling your .NET Framework, which was 2.0 in my case.

    After I did so, I still got this error. I tried to seek help at Microsoft Support, who sent me an e-mail back with these options:

    'Download and run:

    Download and run as administrator:

    Download and run as administrator:

    Then restart your computer and try Windows Update again.'


    I did this, but Windows Update gives Code 643: An unknown error has occured in Windows Update*.

    As I also read on the official microsoft site that 3.5 is an upgrade from 3.0, which is an upgrade from 2.0, I thought I would just need to install 2.0 again, after that 3.0 and after that 3.5.

    When I tried to install 2.0, it said that 'this version is already integrated into the operating system and doesn't need to be installed*'. So I tried to install version 3.0, as the installation of 2.0 didn't seem needed. This installation process gave me the message: 'a higher version of this program is already installed, therefore there is no installation needed*'.

    I also got an error message 0x004484b6, but this was only once (not with the same program with which I got the other error message) and I am not sure whether this is because of .NET Framework or not.

    The .NET Framework can not be seen in Control Panel--> all programs in any of the cases.


    *Note: I briefly translated this from Dutch. Although it is not exactly the error message, the translation coincides with the error as best as I can.

  • Hi Mr. Davis,


    Thank you for posting.


    At first, which software would you like to install on your machine?


    Vista SP2 is including .NET Framework 2.0 SP2 and 3.0 SP2 by default. I would recommend that you could download .NET Framework Verification Tool to verify whether .NET Framework is installed correctly on your side or not.

    Please check the following link:


    If it failed, I would recommend that you might format your OS. Since your OS might be corrupted.
