Can I use an Office 2007 key to activate Office 2010?

brijithlal p k October 12, 2014

When I try to activate my Microsoft Office package, the activation window of Office 2010 appears.

While entering the product key provided, it says it is not a valid product key. I have contacted the help Center and they told me that the product key belongs to Office 2007.

But Office 2007 is not preloaded! I want to activate Office 2007. What should i do?

    No. Your 2007 key will not activate a 2010 product. The manufacturer wants you to buy the upgrade.

    How to uninstall Office 2003, Office 2007 or Office 2010 suites if you cannot uninstall it from Control Panel?

    I agree with DalSan on both points. Download Office 2007 from MS, and once you get it up and running, remove 2010 from the PC so you don't end up with version conflicts.

    You can go to Microsoft's website to download the proper Office 2007 package and install it. You would enter the product key in the process of getting the download, but should fully activate with the product key. Download the appropriate 2007 package here:

    You may want to uninstall Office 2010 prior to installing office 2007 if you are not planning on using 2010 anytime soon or in the future. Even if you want to use it in the future, it is simple to download the package, or another more recent version like 2013. Plus, having 2010 installed not only takes up hard drive suave, but can be confusion in which office version would open with documents (typically you want to install different version of Office in sequential order to reduce issues).
