Microsoft.SharePoint.Upgrade.SPUpgradeException
Just in Case:
After 2 hours finding a solution, i just unistalled INFOPATH 2010, Beta or RTM and i could run SharePoint Products and Technologies without any problem.
Stupid, but works, i don't think i can report a bug from connect because Office Beta ended now.
