Install note (GOG version doesn’t work):

so for those that dont get it still , what you do is unzip the file open the file folder there should be 5 items in total. You copy those items into game folder where it has the .exe which is the game itself . I ran the game from the folder itself like someone in the comments suggested and it opened up for me.
