I recently replaced Office 2003 with 2013, but kept the old version on my computer. This worked fine for a while but for no obvious reason my computer started to associate my Excel files with the old version, and however I tried
I was unable to get the association to be with the new version. This was a real nuisance as I had added in some new macros which weren't easily available to me in the old version. So I uninstalled Office 2003 and this solved my Excel problem. However it left
me without Office Picture Manager which, like many other people posting on this site, I use as my basic picture editor - cropping, auto correcting etc. So I did a custom reinstallation of Office 2003, only installing Publisher. This gave me back Picture Manager,
and therefore solved all my Office problems (so far) as the rest of the Office suite on my computer was 2013.
I did something similar. I purchased Office 2013 for my new computer but really missed all of the great features of Picture Manager and not real happy about MS removing the Charts and Graphs from Access 2013. So I installed my Office 2007, leaving Office
2013 on my computer. I then added the 2007 Access and Picture manager to my task bar at the bottom. Now I seem to have the best of both worlds; at least for now. It really would be nice of MS to have a place where the consumers could post the good and not
so good about the new versions so MS could come out with updates to resolve the issues. That would be awesome customer service.
