I'm trying to download from GOG. I'm using Vista. I've downloaded 3 times. Each time I try to execute, it says files are corrupted. I've used their downloader and the browser one. Still no luck. I disabled my antivirus before trying to execute and that didn't work either. I've tried their forum but I think Gameboomers are more of the "gurus" and respond quicker. Any ideas?

Most GOG games have more than one file to download. Often you may have one .exe file and one or more .bin files. If you don't download all of them, and download them to the same folder, you'll get an error when you try to execute them.

Which game are you trying to download?

Broken Sword 2.

By the way, there seemed to be only one file. About 612mb.
