MS Office 2010 default file associations missing

Running Windows 7 64bit Pro with Office 2010 32bit. It's a new computer and when transferring office documents from one user to another the file associations are missing. You can't open up office documents on the new computer unless you manually associate it. This occurs with all user profiles on the computer except for the local administrator account. Is there a registry fix to run to associate all office extensions to default. It's not a big deal to manually do this but users can't save to sharepoint as it just creates a temp file. Thanks for any help.
