The questions linked in the comment only answer for version of Office when installed but don't really try to answer when there is no version installed

In my test, your variable is always set even when you don't have Office installed....

Add in your For /f loop the 2>nul redirector and your loop will not return any string that defines your variable...

Your if defined are not working....
