golyoscsapagy, I'm afraid snakehead007 is correct. Just saying the game will not launch is not useful information. The game launches fine on my machine.... fine many times while interacting with animals was interpreted by the game as exit to OS with an error code. (A problelm which is thankfully now gone.)
So saying that it's extremely hard to fix your game, computer, electricity supply or whatever is preventing the game from running for you, the immediate questions is what have you tried and what conditions in hungary might be corrupting the game code, if the at is the case.
The first question is are you using a valid and safe version of Microsoft Windows 7 or 10 or are you using an Apple computer or Linux. The game works on Win7 for me.
Next, what have you tried to fix the problem. Games on GOG have an option of verifying the downloaded code. Have you done that? It is possible that you might have a virus or trojan. It's also possible that your antivirus could be blocking the program.
Lastly, you might not really be interested in trying to play the game, but just want to complain. Typing a nine word post lets you do that, but it's not enough for people for whom the game works to take you seriously.
