When you install a new version of Simplify3D, the old version will still remain on your computer. For example, if you were using Version 4.0.1 previously and you now install Version 4.1.1, you would be able to find both versions at the directories below, since the prior version is not modified by installing the new one.
C:\Program Files\Simplify3D-4.0.1
C:\Program Files\Simplify3D-4.1.1
So if you want to run the old version, you can just navigate to the correct directory and double-click on Simplify3D.exe in that folder.
