MS Office 2010 x64

Question

Does  iTunes support Microsoft Office 2010 64 bit yet?
iTunes seems to think I have no Contact/Email etc on my PC.
Thanks

There are many incompatibilities with the 64 bit versions of MSOffice.  MS made the 64 bit version of Office for people with really big Excel spreadsheets and such that need a lot of memory.  But even Microsoft recommends installing the 32 bit version of Office unless you have a specific need for the 64 bit version:

IMPORTANT    The 32-bit version of Office 2010 is the recommended option for most people, because it prevents potential compatibility issues with other 32-bit applications, specifically third-party add-ins that are available only for 32-bit operating systems.
I initially had Office 2010 64 bit, running on a Windows 7 64 bit machine to sync a Windows Mobile 6.1 phone, only to find out that the built-in syncing services of Windows 7 don't work with Outlook 64 bit.  Even Microsoft didn't make the 64 bit version of Office fully functional with their own products!
Unfortunately, you cannot install the 32 bit version of Outlook if you have any of the 64 bit versions of the other MSOffice pieces.  So unless you have a specific need, you should uninstall the 64 bit version and reinstall the 32 bit version of Office.  The 32 bit version of Office will run just fine on a 64 bit version of Windows.
