Often, quite inappropriately... You'll not find many recommendations to do that on this or most other forums I support.

No the status quo recommends to repair Microsoft office however there are issues running multiple copies of ms office together that sometimes arise.

Usually recommendations such as to repair office are normally recommended before re-installation, DE-installation of previous versions, etc. but under some circumstances people who work for Microsoft have recommended to un-install same and other versions of ms office before proceeding installing or re-installing the same or newer versions.

I'm don't believe Microsoft employees are being inappropriate when they have at times under certain circumstances recommended uninstall other or all version of Microsoft Office installed on a PC.

If somethings not part of the status quo doesn't mean it doesn't exist.

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 and use different versions of Office on the same PC"
