RE: Error 8000401a - Windows Live Messenger 2009 (14.0.8050.1202)
I found this on another website and my msn is working fine now that i tried this. Official version of MSN 9.0 can not login after upgrading,
prompt error code 8000401a. Computer does not have to open any firewall
(including built-in system), anti-virus software. 8.5 when the original can,
but after the 9.0 upgrade will not be able to visit the MSN.
Solution: In the "Start - Run" dialog box, type "regedit",
the registry key HKEY_CLASSES_ROOT / AppID find 380689D0-AFAA-47E6-B80E-A33436FE314B
then delete it and it should work fine.
