    "Installer encountered an error: 0x800401f0"

    I've tried to install a Vista update patch (KB941649) downloaded from
    Microsoft web site. I just double the file, but I only got an error message:

    Installer encountered an error: 0x800401f0
    CoInitialize has not been called.

    Googling has not been helpful so far. Does anyone know a solution?
    Thanks in advance.

    Download and SAVE the CORRECT version of KB941649 from these links :

    Vista 32 bit [x86]
    http://www.microsoft.com/downloads/d...displaylang=en

    Vista 64 bit [x64]
    http://www.microsoft.com/downloads/d...displaylang=en

    Save it to the Desktop
    After the download completes close the browser and any other open programs

    Install the update now and then reboot.
