[SilhEo 0]

I think it can help other players, to make it easier to find i'll post here.

 

Its for Windows Seven Users.

 

DEP or Data Execution Prevention is more or less a safety check when installing programs. It looks for anything that could be considered malicious in code and will shut down the action without prompt or reason. This happens alot with 3rd party programs.

 

A full scale description about DEP http://en.wikipedia.org/wiki/Data_Execution_Prevention

 

Here is a very simple way to turn off DEP

 

- Go to START

 

- Type in CMD but do NOT press enter.(i press enter and work , and normal click work also)

- Right click the CMD.exe icon and run as Administrator - verify your command prompt says Windows\System32>

 

- Enter this command exactly as shown

 

bcdedit.exe /set {current} nx AlwaysOff

 

- You must restart your computer for this to take effect

 

NOTE* In some occasions you must turn off UAC (User Account Control)

 

Let's say that for any reason you're ready to turn DEP back on , ok no problem. Same steps but type this-

 

bcdedit.exe /set {current} nx AlwaysOn

 

- Once again restart for this to take effect.
