How to work with self-extracting archives? First of all you need download your game from this site. If you look at file in explorer, icon must look exactly like this image (that's why I edited and updated extractor from TC).

Step 2: Confirm with OK and docompressing will start immediatelly:

And that's it. You may select game executable with right mouse button and create shortcut on your desktop. Launch game by double clicking the executable or shortcut and enjoy!
