Do I have a choice of 32bit or 64bit versions of Office 365 to Install on Zettagrid?

Microsoft recommends the installation of 32bit office 365 unless there is a specific need for 64bit office 365. This recommendation is for compatibility reasons as many applications and office plugins have only been tested with and support 32bit Office 365.

The 64bit versions of Office 365 are only recommended for Excel users with large spreadsheets (2GB or greater) and Project users dealing with large and complex project files.

For these reasons the 64bit Office 365 is only available by special request.
