I followed the instructions in prophet.nfo file (which can be opened and read using Notepad or something; it’s not a “system information” file). Extremely simple and straightforward. Not sure why some people are getting that “this is not the .exe you are looking for” message. The only thing I can think of is I ran Steam before starting the game, but it sounds more like a problem that would be caused if the crack files weren’t copied over correctly?
