Can I have both versions of Microsoft Office on same Windows? for example, Office 2007 (32-bit) and Office 2013 (64-bit).

On answers.microsoft.com (the worst forum ever seen in my life) it was said, that's not possible.

Any ways?

The official line by Microsoft is that this is not possible. The real answer is that it's possible but a bit complicated.

The simple solution is to install one of the versions in a virtual machine, which might be too heavy.

In the article Installing 32bit and 64bit Office versions together, the author was in contact with a Microsoft developer who gave the following rules for the installation of multiple Office installations:

  • Install the 64 bit versions first, from oldest to newest
  • Then install any 32 bit versions, again in order of oldest to newest
  • Do not try and install 32 and 64 bit versions of the same Office version (for example one should be version 2016 and the other 2013)
  • Only have one version of Outlook installed.

If one of the versions refuses to activate, use the following commands:

cd  "C:\Program Files (x86)\Microsoft Office\Office{number}"
cscript ospp.vbs /act

This article dates from 2013 and relates to Office 2013, so the solution has still to be tested with the latest Office version.

    I've tried this and confirm it worked. (installed 2010 x64 and 2007 x86 ) – T.Todua Nov 11 '18 at 18:16
  • In my personal experience, that advice is still valid ten years later. Note that Office 2016, 2019, 2021 and 365 are all the same version internally (v16.0), so they can't be installed in parallel. – Heinzi Sep 20 '23 at 15:15
