Is anyone a computer wizard? I need help.

<p>When trying to sign in to MSN messenger, a popup appeared saying that I needed to upgrade to the new version. When I tried to download it, it says it was not able to install and it gives the error message: hr:0x80070643 . I looked ALL over the internet for solutions and tried for AT LEAST an hour and a half trying all the solutions, but I couldn’t figure it out. </p>

<p>I also heard that error message has something to do with Windows Update, but my Windows Update always fails when I try to update.</p>

<p>Please don’t say “Go see a computer specialist” because I don’t want to have to pay 50-100 dollars for them to look at my computer.</p>

<p>If you know what I should do, lemme know please! I just wanna talk to some international friends via MSN/Windows Live Messenger!</p>

<p>[Error</a> message when you use Windows Server Update Services Setup: “Error 0x80070643: Fatal error during installation”](<a href=“http://support.microsoft.com/kb/920660]Error”>http://support.microsoft.com/kb/920660)</p>

<p>…tried that yesterday</p>

<p>[url=<a href=“http://support.microsoft.com/kb/958052]You”>http://support.microsoft.com/kb/958052]You</a> receive error code 0x80070643 or error code 0x643 when you use the Windows Update or Microsoft Update Web sites to install updates<a href=“This%20one’s%20different%20from%20the%20above”>/url</a>. </p>

<p>643 is Windows Installer error. I’m pretty sure it has something to do with your Windows (Automatic) Updater (which you said isn’t working). Fix that and you fix your problem.</p>

<p>Maybe uninstall your current version, then download the full package of the latest version (instead of just the update) and see if that works?</p>

<p>For now, you can use Web MSN or some other online messaging client like ebuddy.</p>
