Just DL'd from Technet and installed. Uninstalled Office 2007 cleaned registry and install went fine with no error messages. Haven't really used it yet. Called up one excel file and it loaded with no errors. Everything else boots up with no errors. Outlook is working fine.
I exported all of my .pst's from 2007 and was prepared to import into the new module and when I called it up It had all my mail accounts already configured with mail in the boxes. DUH! I must have left some files on my disk that the install found.
In answer to the question about beta 2. It doesn't say beta 2 but the ver is 14.0.4536.1000 (64-bit)
