Zip link isnt dead I just checked it even though I already have Mopar.
If you need the linux download, just download the regular MoparScape 3.2, extract it, and in the folder the RunMoparScape linux file is there for you to run.
If you need the mac download, do the same as above.
Use the MoparScape.jar to run it on Mac.
Or use the linux one for mac as well.
