How to install different versions of Microsoft Office on the same computer

Table of Contents

Case #

You need to have different versions of Microsoft Office on the same machine. There are limitations when allowing co-existence of different Microsoft Office versions.

Solution #

The following Microsoft article presents the considerations and limitations of having multiple Microsoft Office versions installed on the same machine: .

Pay extra attention to the Microsoft product lifecycle and corresponding supportability statements for each installed version of Microsoft Office. For example if you have a very old version installed (e.g. Microsoft Office 2007) and co-existing with Office 365, you will not be receiving support or security updates for the old version.

Also pay extra attention to the bittiness (32-bit vs 64-bit) of the installed Office apps. It is a hard requirement that all co-existing versions have the same type of bittiness, i.e. all co-existing Office apps must be either 32-bit or 64-bit. No mix and match is allowed.
