hi
Do you have this error?
Resume:
1- From the Control Panel\All Control Panel Items\Programs and Features, Remove the Windows Live Sign-In Assistant.
2 - Download-it from http://www.microsoft.com/downloads/details.aspx?familyid=5E193CFE-F45A-4E29-B6B7-984E7802C639&displaylang=en (chose the right version, 32 or 64 bits).
3 - Install-it, works fine for me.
