If you’re looking to install and run more than one version of Microsoft Office on the same PC, here’s what you’ll need to do:
Install earlier versions first
It’s important to always install earlier versions of Office first. If you don’t, you’ll likely get setup errors. For example, if you install Office Home and Student 2013 and then try to install Office Home and Student 2010 on the same PC, you may get this error:
There was a problem setting up Microsoft Office Home and Student 2010.
To avoid these errors, follow this installation order:
|Microsoft Office 2003 suites or programs
|Microsoft Office 2007 suites or programs
|Microsoft Office 2010 suites or programs
|Microsoft Office 2013 suites or programs
Important Even when you follow these recommendations, you may have problems running Office 2013 and 2003 programs on the same PC.
Tip If you need to uninstall the latest version of Office, see Uninstall Microsoft Office 2013 or Office 365. If you need to uninstall Office 2010, see How to uninstall or remove Microsoft Office 2010 suites.
Don’t mix 32-bit versions with 64-bit versions
32-bit and 64-bit versions of Microsoft Office programs don’t get along. If you try to install a 64-bit version of Office on a PC that has a 32-bit version of Office, you’ll get an error, and setup will tell you to remove the previous version.
If you want both versions of Office on your PC, choose to have either all 32-bit versions or all 64-bit versions of Office.
Having two versions of Office on the same PC can sometimes create other problems. For more information, see the file type association problems section in the Office 2013 known issues list.
