Should you install 32-bit or 64-bit version of Microsoft Office 2010?

How to choose between 32-bit and 64-bit versions of Microsoft Office 2010?

Microsoft Office 2010 is the first version of office that will ship in both 32-bit (x86) and 64-bit (x64) flavors. If you are running a 32-bit version of Windows, you can only use a 32-bit version of Office. However, on x64 Windows, you can decide to install either 32-bit Office or 64-bit Office, but not both. Microsoft has just published an article which helps you make that decision.

In short, they recommend installing the 32-bit Office, even on 64-bit Windows, unless you have special needs that require the use of 64-bit Office apps. For example, one of the cases where 64-bit helps is working with huge (over 2GB) Excel or Access files. Read the article for more information.
