install issue

i have half-life 1

i have steam

i start the .exe and get all the way to where you actually hit the install button but it doesn't let me,

the path says: c:\program files\steam\steamapps\dismantle43\half-life

and the install button is unclickable


any ideas?

Yea this will fix it so pay atention.

Start Half Life 1. Play the tutorial level or just start the single player game.

As soon as you get into the game you can either play on or exit the game.

You will now be able to install ESF.
