if you use a shortcut then the shortcut is setup incorrectly
That is my steam shortcut, but i'll tell you how to get it to work for won.
Right click on the ESF shortcut and then click on properties. In the Target box put the path to your hl.exe (for instance c:\sierra\halflife\hl.exe)
In the Start In box, write C:\sierra\half-life (Your hl directory) and then click ok.
Then try and run it again
