Don't mind the OS. I am early for work so I used our procon server via remote desktop to start this endevour.
To clarify this is every single version extracted in between.
I have no clue if the install process cleans up any of the excess files. First order of business is analyzing what has been left behind. I may actually install all the versions if I end up waiting in the hospital again or something. I would out of the box expect things like the old editor to be part of the left over files etc.
