32-bit of Office is the default choice. Computers running 64-bit versions of Windows generally have more resources such as processing power and memory, than their 32-bit predecessors. Also, 64-bit applications can access more memory than 32-bit applications. Therefore, if your scenarios include large files and/or working with large data sets and your computer is running 64-bit version of Windows, 64-bit is the right choice when:

  • You’re working with large data sets, like enterprise-scale Excel workbooks with complex calculations, many pivot tables, data connections to external databases, Power Pivot, 3D Map, Power View, or Get & Transform. The 64-bit version of Microsoft 365 may perform better in these cases.
  • You’re working with extremely large pictures, videos, or animations in PowerPoint. The 64-bit version of Microsoft 365 may be better suited to handle these complex slide decks.
  • You’re working with files over 2 GB in Project, especially if the project has many sub-projects.
  • You’re developing in-house Microsoft 365 solutions like add-ins or document-level customization. Using the 64-bit version of Microsoft 365 lets you deliver a 64-bit version of those solutions as well as a 32-bit version.
  • You’re working with the Large Number data type in Access, and while this data type is supported by 32-bit Access, you may see unexpected results when executing code or expressions that use native 32-bit VBA libraries. 64-bit VBA provides the LongLong data type which fully supports large numbers.

For more information please refer to Choose between the 64-bit or 32-bit version of Officeopen in new window.


If you are using ARM64-based Windows, you can select ARM64 (64-bit compatible) for better performance and compatibility.

Update channel

You can add one or more languages that you want. The first full type of language in the list determines the Shell UI culture, including shortcuts, right-click context menus, and tooltips. If you decide to change the Shell UI language after an initial installation, you have to reinstall Office.

If you do not add a language, Office will automatically match the system language, or fall back to the language specified in Advanced settings - Installation settings - Fallback language if the system language cannot be matched.

If you check Deploy proofing tools only, the language will be installed as proofing tools without display language.
