RE: Roll Back to previous version
You can download and extract as many versions as you like from the prusa slicer github downlad page and run them directly without installing anything. The only problem comes from if the configuration files between different versions. For example 2.4 wont work with a config thats been updated to 2.6.x for example.
However you can still run them if you manually specify the configuration folder location during execution (well you can on windows, not sure about the mac procedure for that). If the location you specify doesn't already have a config structure in it then when the software starts its like a new install, it gets you to go through the wizard etc.
Its how I run multiple versions for testing and debug. For example I will have all my versions in different folders, 2.4, 2.5, 2.6 etc and then in each folder I have a simple batch file that I can run with "prusa-slicer-console.exe --datadir settings" in there. That will look for and create a 'settings' folder in each directory where it will use for the config data. That way I can run multiples without changes in one effecting the others. Run the exe without the datadir switch and it uses the normal system location for the config.
Uninstalling does not get rid of the configuration folder so it can be hard to roll back. PS does have a Configuration>Configuration Snapshots menu item that allows you to roll back to previous config versions but I don't know how far back that goes.
To do a complete wipe you would need to delete the config folder too manually after uninstalling the software. Either delete or rename it, if you want to have the option of using it later. Before doing that though make sure you use File>Export>Export Config Bundle (either with or without physical printers) first. That will export a file with any CUSTOM print/filament/printer profiles that can later be imported into any other install. It wont save profiles added by the initial config wizard but it will do everything else. If you added anything via the wizard then you can always it it again the same way.
