where can i find this file?

Hello,

Please open the .rar file you downloaded using only WinRar, which can be downloaded from www.games4theworld.org . (If you use any other software than WinRar, like WinZip or 7-zip, the files will get messed up!)
When you've opened the file using WinRar, select áll the files in it and drag & drop them to a folder on your Desktop. When the extraction is done, close the .rar file and open the folder on your Desktop.
Now, start by reading the included "# Installation Guide.txt" and you should be able to get the game to work yourself. Good luck!
