I have two different 3d printers. I only print for fun. The older one is a New Matter Mod-T which needs the 15.04.6 version to slice. The other newer printer is an Ender3 Pro for which I would like to be able to use updated versions of Cura. Am I able to load both versions on my laptop? I am afraid to get rid of the 15.04.6 in case I can't get it back again. Thanks for your help.
