    Unhappy Cant Install Windows Live - error code 0x80070643

    Recently i got the mandatory message about Windows Live Messenger, about how we must upgrade. Ive been tryin to do so for some time, unsuccessfully.

    When i download the installer, it begins, I choose what I want to install, it begins, gets to the end, then tells me an error has occurred.

    The error code is 0x80070643.

    Can anyone please help me. I use windows Vista 32bit.

    Thank you thank you thank you.

    Default

    Try this to fix it (and it worked) was to go to
    Start>Run, type 'cmd' and then enter each of these one at a time at the
    command prompt (hit 'enter' after each one if needed):

    regsvr32 wuapi.dll
    regsvr32 wuaueng.dll
    regsvr32 atl.dll
    regsvr32 wucltui.dll
    regsvr32 wups.dll
    run some registry cleaner (reginout) to fix up ur registry errors
    It also fixes an issue where you keep getting messages from the security
    center saying automatic updates are off when the automatic update window says
    they are on.

    Default windows live

    If you dont have Revo uninstaller get it,then completely remove it By Using the "Advanced" option (the 1 at the bottom) If windows asks to reboot Dont , and continue to delete all reg entries and any trace if it 1st (MAKE SURE YOU ONLY DELETE THE THICK BLACK TEXT) then use a reg cleaner , reboot, cross your fingers and try again

    (MAKE RESTORE POINT FIRST!!!!!)
