    I have been prompted by my computer (I'm using Windows Vista) previously to
    install the new Windows Live MSN Messenger for the past couple of weeks. Up
    until last week, I have been able to still sign in and use the previous
    version. Since trying to update my version to the latest MSN Messenger, it
    will fully load the installer, and then come up with the response:

    Messenger couldn't be installed because we had trouble installing this
    "Microsoft Application Error Reporting, An error occured during the
    installation of assembly
    'Microsoft.VC80.CRT,version= "8.0.50727.42'"
    Please close all other open programs, and then try again. It looks like
    another program is preventing the installer from working. hr:0x80070643"

    So far I've tried countless times to run the Installer, and also tried to
    install WLM in a "Clean Boot" install, then in "Normal Mode", none of these
    have worked, I'm at my wits end! Any help massively appreciated, thankyou!

    Thanks for your post, however I've tried to do that but it didn't work and
    signed me back out almost instantly, and I no longer have the old version of
    MSN (8.5) on my computer.

    Does anyone else know how to get the new version to work?

    Looks like we're all stuffed mate! This seems to be a massive problem
    why they forced this joke of an upgrade upon us is anyone's guess! Look
    like we're going to have to look elsewhere for a messenger program

    So what are we supposed to do then if we can't recover our msn or download
    the new one - this is stupid!
    I use that as a major form of communication with my contacts. Is there no
    where that we can complain directly to the people who have caused this
    problem for some of us? How the heck are we supposed to find a solution
    without being able to contact some official Microsoft help desk or whatever.
    That's just great - now we have to transfer all our contacts & inform them
    all about changing messengers? How do we convince them to sign on to another
    messenger if theirs works fine for them? No guarantees they will get another
    one just to talk to one person.
    This is terrible - leave Microsoft customers out in the cold. What kind of
    services to they offer anyway. People buy their stuff & they don't care if
    one of their products fails, even for the minority. Poor customer service.

    I am completely disappointed with this company. I have spent my hard earned
    money on their products - the least they can do it make sure this one works

  6. Greetings -

    Solution for you or anyone who has or is currently having Messenger installation issues. The forum link below solved the following error:
    "Network error occurred while attempting to read from the file:

    Please close all other open programs, and then try again. It looks like another program is preventing the installer from working. hr.0x80070643"

    If you have this message, and you haven't found a solution yet, then this will do the trick. Although it's an older post, it works just fine for the current 14.0.8117.416 Messenger update issue:

    Scroll about halfway down the page. Look for Microsoft Customer Support (Joan, Technical Support, Live Essentials):

    Note: For the Windows Installer Cleanup Utility, I downloaded from this link (you'll want the latest version wherever you get it -
    **This utility works for XP/Vista/Windows 7.

    After all the time I spent looking for a solution, this took 10 minutes to solve. I hope it works for you as well. Please pass along. Thanks. Deb
