Installing Office 2010 and SharePoint 2007 on the same box will ruin your day

if you are seeing this error "SPUpgradeException: One or more types failed to load" exception when running configuration wizard" it's most likely because you installed office 2010 on your SharePoint 2007 box.  I wasn't able to create web apps or deploy certain features.  I solved the issue by removing Office 2010 and rebooting.
