    Data Execution Protection - wth?

    I have used the command prompt to disable DEP, or so I thought (bcdedit.exe/set nx AlwaysOff). But if I use the favorites folder off of the start menu without starting internet explorer beforehand I still get the DEP error message and IE will not start.

    A minor inconvenience, granted. But how can I be getting a DEP error when I have it turned off... I don't understand.

    I started searching for answers and stumbled on this forum. Nice place . Wasn't sure which topic this question was for, so if this is the wrong one, I apologize.

    Let me suggest that you might want to find out what's causing the DEP
    exception in the first place and correct it, instead of turning off DEP.

    From the sound of it, the problem is almost certainly being caused by an
    extension / add-on for IE7. Did you try the Manage Add-Ons dialog in IE7 yet
    to see if you can find the culprit?

    I see, I did notice (after I wrote this) that some bookmarks work without error. I'll look at those add-ons and try to determine what's going on.

    Well, I looked at the add-on manager, but I'm at a loss as far as trying to determine which one might be the problem. I still don't understand how dep is shutting down IE7 when it is suposed to be off though ???

    There's also an Execute Bit setting in BIOS for Intel CPUs. If you
    have a recent Intel CPU, did you try disabling that setting?

    Hello Cuisi,

    IE7 has a separate DEP option as well for security.

    To test and see what add-on is causing this problem in IE7, see this tutorial.

    Internet Explorer - Reset


    To turn DEP off in IE7 as well, see Option Two in this tutorial.

    DEP - Enable or Disable

    Hope this helps,
    Shawn

    Thanks for the replies. I checked the IE option and it says it is off. But I'm not sure if the default it is using when opening favorites is 64 bit or 32 bit as I seem to have both versions on this system. Something else for me to look at...

    Cuisi,

    It should be the 32 bit IE7 it uses by default. "C:\Program Files (x86)\Internet Explorer\iexplore.exe".

    Re: Data Execution Protection - wth?

    Yes, you're right it is 32 by default. So I'm even more at a loss then I was, since I have it turned off there (as it shows in that tutorial) as well as having it off in the OS settings. Yet it still kicks in and shuts down IE 7 when I click some links in my favorites folder.

    Here is something else I noticed. It only kills it if I have no instance of the browser running and go straight to my favorites. If I have it running and go to my favorites, it starts a new browser window and goes straight there with no problems at all. I give up, I'll just start the browser before I go to my favorites I guess.

    That is strange. You might run a sfc/ scannow command to see if it can find and fix any bad system files that may be contributing to this.

    System Files - SFC Command

    Hope this helps,
