The SL-32.exe is a file for legacy operating systems, have you tried opening the game by just clicking the SL.exe?
I don't think so, I've already downloaded the ziped file three times and got nothing, the same message all times. I've tried to download and run other games even TFTUV work just fine with the same options in my antivirus. I'm using kaspersky.
I'm a bit sad cause I'm running out of solutions for the problem
