This product includes both 32- and 64-bit versions for a single computer. We recommend the 32-bit version, which runs great on both 32- and 64-bit versions of Windows. People who routinely use very large documents or spreadsheets that need more than 2 GB of memory may want to run the 64-bit version, but many common add-ins for Office don't run correctly in the 64-bit edition.
