This is a save game where the storyline is completely completed, but the auto-save is a new game where there is a lot of money and some of the achievements are open. So you can play just enjoying the game, in addition to the auto-save, there are saves at different difficulty levels and all the technology schemes have already been collected, these saves are packed into a self-extracting ZiP archive and the unpacking is designed for new systems such as Windows Vista, Windows 7, Windows 8, For those who installed the game on earlier versions, I suggest you unpack it yourself using any archiver into the Application Data directory...

P.S. Passed it myself on Windows 7 x64 bit
