Should I choose Office 32-bit or 64-bit? How do I install 64-bit?

Microsoft recommends that you do a 32-bit installation in almost all cases, the reason being that you can use add-ins that don’t work on 64-bit. Only processing very large documents, spreadsheets and database files can be a reason to choose 64-bit.

  • Not using large files? Then go for 32-bit!
  • Not sure what to choose? Then choose 32-bit!
