Fallout 3 image error



So i bought Fallout 3 started playing it using the disc and now i want to play without the disc in the drive. I made an image using alcohol, clicked on SecuROM in extra emulation. I have the image but when i try to launch the game i get this message.

Conflict with Emulation Software detected.
Please have a look at http://www.securom.com/message.asp?m=emu&c=2500 for further, more detailed information.

I went through those steps and it still doesn’t work.

any suggestions>
