Uninstalling Microsoft Office

The Technology Support Center recommends that you uninstall your existing version of Microsoft Office before installing the latest version to avoid technical issues that may arise from having more than one version installed.

Before You Begin

The version of Microsoft Office that you download and install from Office 365 will not replace any existing versions of Microsoft Office on your computer. While it is possible to run more than one version of Microsoft Office at the same time, the Technology Support Center recommends that you uninstall your existing version before installing the latest version to avoid technical issues that may arise from having more than one version of Microsoft Office installed.

If you choose to uninstall your current version of Microsoft Office, you should keep your product key on file. When you leave Illinois State, the version of Microsoft Office that you installed through Office 365 will expire and will no longer work. After leaving the University, you may want to reinstall your previous version of Microsoft Office, which will require your product key. For more information, see 739: Identifying your Microsoft Office Product Key.

Uninstalling Microsoft Office will not remove any documents, spreadsheets, presentations, etc. on your computer.
