Installation Source Registry Key
Generally there's a better way to do this for products that are both installed via the Windows Installer service and support updating from one version to the next. Use the upgrade code, which you get from the Property table of an Office MSI file. I don't have a bunch of Office versions to compare, but if they've taken their own advice and kept the upgrade code constant across versions, then you can call MsiEnumRelatedProducts to get the product code for the version of Office that's installed on your machine. With the product code you can call MsiGetProductInfo to get the install location, the version, the date it was installed, a list of transforms that were applied to the install. Lots of stuff. Do it this way, and you don't have to worry about not being able to detect some future version of Office. This is the documentation you want to be looking at.
