Is there a way for a Mac user to do this? I have seen two others ask this question but no one has answered them. If anyone knows how to get an .exe file running on a Mac, that'd be terrific, but as of yet, downloading it via MTS doesn't allow for any other platform than Windows.
You could try to run it with Crossover. http://www.codeweavers.com/products/cxmac/ There's a free trial or a torrent somewhere on the web.
It's an emulator, so no need to actually install Windows on your beloved mac. I find Crossover to be kind of wonky though, not every program you run with it works properly. I'll try to run s3pe with it myself when I find the time.
