@dawgoneit Never mind. That’s fine.
I am not at home at the moment so unfortunately I cannot post screenshots of the installation dialogue.
When you execute the setup you come to a point where you are asked about to install into a directory, usually that is
C:\Program Files\TripleA\
Now the task is not to install another version into the same directory - in that case you would overwrite the present installation - but into a different one.
So when it comes to the above mentioned dialogue simply click into the line where the installation path is indicated and change it to
C:\Program Files\TripleA_whatever\
You will then install another version side by side.
Later be sure to know which version you open with which shortcut/icon on your desktop.
