Hi Kevin,

Microsoft don't recommend it, however I have had more than one version of Office installed on a PC - but generally run into some problems.

What I have found is that if you try to run multiple versions, sometimes one (or both) versions complain that files are missing/corrupt/changed and need reinstalling.

Because the Office suite comprises a lot of shared files, not just files specific to each program, installing multiple Office versions can cause these shared files to be inconsistent to the version of the program you are running.

So if you start Word 2010 but Excel 2013 has installed/overwritten an Office 2010 file that Word 2010 is looking for, Word 2010 might complain.

Similarly, Excel 2013 might complain that it is seeing files from Office 2010 that it doesn't like.

Give it a go Kevin.  I can't guarantee that it will work without issue, but you might by able to get by with just some minor annoyances.

regards

Phil

I know what you mean - on an old box I used to run Office 2003 and Office 2007 and although it didn't seem to cause problems, Office was forever re-configuring itself.

However the issue here is whether or not it will let me install just the one Office 2013 component, ie. Excel, and not any others.

When I click setup.exe on the CD it objects to the fact that I already have Office 2010 installed - it says it can't install 32-bit Office because I am already running 64-bit Office 2010.

OK, so I go down one level to the office folder and click on setup64.exe.

This time it asks for my product key and once I enter it, it installs all of Office 2013. It doesn't give me a choice of which Office component I want to install - I'm sure that in previous versions you could pick and choose, eg. Word and Excel only.

What am I doing wrong, or can't it be done? Is Office nowadays all or nothing?

Hi Kevin,

Seems that since 2013 you can't choose which programs to install, at install time.  However you can use the Office Deployment Tool to configure the Click to Run installation, which allows you to tell C2R what programs to install.

Good luck.
