You can’t upgrade from 32 bit Office 2007 to 64 bit Office 2010 directly, you have to uninstall existing 32 bit Office products prior to install 64 bit Office 2010.


But 64 bit version Office 2010 must be installed on 64 bit windows operation systems. 32 bit version works on both 32 bit and 64 bit windows operation systems.It’s recommended to install the 32 bit version Office 2010 due to compatibility issues however if you still want to try 64 bit version keep these in mind. When you download from the volume license site, MSDN or Technet.you get a warning suggesting that you use the 32-bit version.

Office 2010 is the first release of Office that contains 64 bit edition. Microsoft strongly recommends, even with 64-bit operating system that people standardize on the 32-bit version of Microsoft Office 2010 for the time being.
