Help please - I am a super-computer-dummy and I just really want to play this game. I am a Mac user and have Yosemite 10.10.5. I have installed the Wineskin and unzipped it and try to use "Choose Setup Executable," and then it needs me to choose a program to install it, and I don't have/can't find one. Where do I go from here? Please & many thanks!
