Half-Life mod Sven Co-op missing executible

http://askubuntu.com – I recently installed Half-Life via Steam on my new computer with Precise Pangolin. The game worked perfectly fine until I decided to install my favourite mod Sven Co-op. At first I installed it the proper way (works on windows) which is to paste the folder into the Half-Life folder, and on Steam it's suppose to appear as a game. When I pressed "play" it gave me an error saying "missing executable". Then I decided to copy the starter/executable/binary files from the HL folder into the SC folder and restarted Steam and got the same error. Both methods were tried with offline mode in Steam as w (HowTos)
