Sometimes you need to remove all office apps from a device; for example Office 365 is often pre-installed onto many PCs by the vendor, however this version is not compatible with business licensing and needs to be removed so that the correct version can be installed.

The easiest way to do this is with the Microsoft Easy Fix Tool provided as option two on this page (Note that you will need to have local administrator permissions to run the app).

We recommend that the PC is rebooted after running this tool, and before installing the new version of Office.
