Please make sure you have STEAM and HALF-LIFE 1 installed. If you attempt to install Earth's Special forces and or Half-Life 1 without steam or its requirements. I'm afraid we won't support nor help you further until you get a valid copy of Half-Life activated on Steam. If you've done that, you are free to ask for any help that you encounter. Also do remember that this mod will <b>only</b> work with Half-Life 1. This means it won't work on Counter-Strike, or any of the source versions (Half-Life 2, Counter-Strike 2, etc)
- Make sure that you have opened Half-Life 1 at least once.
- Run the installer, select the "I Agree" button and hit on the next button.
- You should see Destination Folder. Make sure it says something like this. c:\program files\steam\steamapps\accountname\half-life\
- Wait for it to install. Once it's done it should say Completed. Hit close. (Install box gray? Launch Half-Life once through steam!)
- Restart Steam or launch steam if you never done so.
- Go to Games, and you'll see Earth's Special Forces in the game list!
- Enjoy!
