Sign in to the Office 365 portal and choose Install.If none of these situations apply to you, the 32-bit version of Office is probably a decent choice. You’re developing in-house Office solutions, like add-ins or document-level customizations.The 32-bit and 64-bit versions of Office programs are not compatible, so you cannot install both on the same computer. You want to keep the 64-bit version of Office that you’re already using.You’re working with files over 2GB in Project 2013, especially if the project has many subprojects.The 64-bit version of Office may be better suited to handle Word documents with large tables, graphics, or other objects. You work with extremely large Word documents.The 64-bit version of Office may be better suited to handle these complex slide decks.
