Dolphin Emulator concerning DEP

Okay i have downloaded dolphin a game for it. The problem is that when i try to execute the game, the screen turns grey and once i close the game a message appears saying that DEP has prevented it from playing. I have tried adding DOlphin to work without DEP but it says that Dolphin must run with it. ANy ideas on how to either work Dolphin with DEP or just work DOlhphin some other way? (p.s I'm using vista)

 

You can turn off DEP for specific programs.

If you are using XP:
Start -> Control Panel
Open the "System"
Click on the "Advanced" tab
under "Performance" click the "Settings" button.
Click on the "Data execution prevention" tab.

It should default to "Turn on DEP for essential Windows Programs and SErvices only"

If it's not on that setting, turn it to that setting. If it is on that setting, then turn it to the other setting and add Dolphin to the exception list.

 

I can't put it into the exceptions list. When i try to it states that "This program must run with DEP enabled. You cannot turn off DEP for this program." What do i do then?
