Make sure you install to Steam, if you have it. If you don't, read the full step-by-step installation guide here.FAQ Sticky said:I have all the right requirements to play ESF, but the install button is greyed out!
You need to have run Half-Life at least once before you try to install ESF. To do this simply start a single player mission. You may exit the game once it has loaded up. After you have done this, you should install ESF.
