Install and use multiple versions of Office on the same PC

If you want to install and run more than one version of Office on the same PC, here are some tips to help you avoid most set up errors:

  • Install earlier versions of Office first. For example, install Office 2010 before installing Office 2013.

  • Make sure all versions of Office are either 32-bit or 64-bit. You can’t have a mix of both.

Keep in mind that even if you follow these recommendations, you might still run into issues when you use two versions of Office on the same PC. If you decide not to keep both versions and you uninstall the earlier version, you might need to repair the version remaining to make sure that the file associations will work correctly.
