A post to a Windows Secrets Column in 2009 states that Windows Mobile Device Center is not compatible with 64-bit Office. Since Windows Mobile Device Center v6.1 is available in 32-bit and 64-bit downloads for WINDOWS versions including Windows 7, surely the 64-bit version should work with the Microsoft Office 64-bit version installed with 64-bit Windows???
