No se instala el juego, update fail y no me deja jugar

usa google translate si es necesario

I don't speak enough spanish to describe this for you natively, so I apologize in advance if this makes it difficult.
1) sign up to this forum http://darkmatters.org/forums/index.php?/files/file/91-community-patch/
2) download the patch from the link, it is supported in many languages.
3) follow the steps within the downloaded file
4) enjoy the game

if you mean you can't play game after installation, try this - "Scan \ import games folder" button from gog galaxy
