On Steam: You must install Steam, open it, open the "my games" windows, download Half-Life in Steam. Then you install ESF in the folder /Steam/Steamapps/
[email protected]/Half-Life/
On Half-Life: You install Half-Life, update it to the newest version, and install ESF in the folder /Sierra/Half-Life/
Second: install EVM on your desktop or some. Than copy the files in your ESF folder ( /Half-Life/esf)
