This article might help explain the difference.

32-bit (x86) or 64-bit (x64) of Office 2010? My Digital Life

If a computer is using Windows 7 64-bit (x64) then either version of Office 2010 should work. But if a computer is using Windows 7 32-bit (x86) then only a 32-bit version of Office will work. The advantage of using Windows 7 64-bit is you can use more RAM (32-bit is limited to about 3.25GB of usable RAM.) So if you have to run several Office applications at the same time (like several spreadsheets, etc.) then the extra RAM should give you an improvement.

The advantage of 64bit when it comes to office and memory is really for handling very large datasets. But keep in mind that a very large dataset for Excel is a single spreadsheet file that is 2GB in size.

For compatibility issues with 32 bit plug-ins for Office, Microsoft recommends that you run a 32bit version of Microsoft Office. Almost all business environments continue to use the 32bit version of Office....and obviously business users have lots of simultaneous applications open all day long....and nearly all business users have 4GB of RAM or less.
