    Hi folks

    This may seem late to the game as all prior posts appear to be at least a
    year ago, but I was just asked to solve this riddle. Been trying to solve it
    for the past 5 days and have run out of patience.

    Running XP (Home) 5.1, Service Pack 3, 32 Bit. Plenty of memory available.
    Have ZoneAlarm Extreme Security running (but not getting any messages
    indicating the problem lies there).

    Trying to download & install .Net Framework 3.5 Service Pack 1 and .Net
    Framework 3.5 Family Update for .Net Versions 2.0 through 3.5.

    Seem to be going in circles. Can't install - get a 645 error code.

    Asked MS, but no response yet. 5 days??

    According to Add/Remove, these versions of .Net already installed:

    Version 1.1
    Version 2.0 Service Pack 2
    Version 3.0 Service Pack 2

    AND, although I keep receiving instructions to install Version 3.5, I see
    Version 3.5 on that same list!!!

    I tried to follow MS Article ID 923100 on what to do when you receive an
    Error 645 code - which says remove all versions and then re-install all
    versions that were previously installed - but got nowhere fast.

    I was able to remove Version 1.1, but could not remove any of the other
    versions. Kept getting the message that "can't be uninstalled, affects other
    apps installed....See Link ID 91126". No joy there either.

    So, I reinstalled Version 1.1.

    Still can't get MS to recognize the Version 3.5 that my Add/Remove list
    shows. And, still can't get MS to stop telling me I need to download &
    install 3.5 SP 1 & 3.5 Family Update. Grrr.

    Still with me?

    There's a security update that's critical but I can't download that until
    ..Net is updated.

    Has anyone figured out what is going on with this program and what the
    answer is?

    I'd really appreciate any help. Read all the other posts but didn't see any
    solution that differed from following MS advice on what to do if you get a
    645 (and 643) error code.

    Anything new?

    Anything that works?

    Thanks to all. If you got to this point, thanks for your patience too.
