"...Another installation is in progress..." or error code 0-1018 when installing Office

When you try to install Office you may get the following error message, or an error message that contains error code 0-1018:

We’re sorry, but we could not start your Office installation. Another installation is in progress, please try again later.

This error can occur if an Office install, update or uninstall was running before you tried to install Office.

If you can't find an Office icon in the system tray, uninstall Office using the easy fix tool, and then reinstall it:
