Just go to MS Office, download a free trial, enter the product key from the MS Office software that you purchased, and voila! So easy!
Does this solution work on different versions of software (in this case MS Office)?
How to Get Microsoft Office for Free in 2020
I don't keep up with all the releases so the dates are probably wrong in the following examples. Lets assume I owned MS Office 07 and I wanted to use your solution.
I assume the MS website DOESN'T offer free trials of outdated software. So, I go on their website, download MS Office 2011 and then enter my product key from MS Office 2007.
Are you saying that will work?
Personally for me, I don't give two hoots about getting the latest MS Office. So, if I have a working copy of an earlier edition, that's the one I want to install.
And yes, for you NO-NO people, I do remove the software from my previous computers when I do this before I sell them.
Even if I could upgrade my previous version, I wouldn't want to as it would be a waste of my time during the learning curve. In fact I'm paying this penalty now in that I'm using MS Office 08 that my wife bought (3 computer version) and insisted I put on my computer to help her on her's.
I was using MS Office 03 and hate the 08 pull down menus. Since I use the program infrequently, I find myself staggering around trying to find this and that when with the '03 version, it would be simply click and done.
