    Hey guys As some of you might know I've been having issues with Vista not executing a program i wrote, i finally found a work around to that problem, but now Vista is pulling some new stunts! As soon as my app calls the an external DLL(it contains methods to connect and communicate with an external device) the program crashes! I little vista bubble pops up saying "To help protect your computer Data Execution Prevention has closed [program name], click here to learn more." So i click it and find that there is an exception list i can add my app to, i select my app to add it to the list and im greeted with a message box that says "This program must run with Data Execution Prevention (DEP) enabled. You cannot turn off DEP for this program" I dont know anymore, this is really frustrating. :sigh: Does anyone have some suggestions for me? maybe turn DEP off completely? Thanx

    You are not the only one with this problem. ANTS Profiler does the same if you feed it an assembly with tail calls (I believe this is cause by an offset that is 16 instead of 12 or vice versa, but it takes just one wrong step for DEP to kick in).

        The external component is writing to unallocated memory. In previous OS's this would go unnoticed. Vista actually protects you against malicious use of this scenario. Turning DEP off wont help in Vista, you will still get an exception (attempting to write to null pointer or something). I suggest you contact the authors of the external DLL and ask them to advise you on getting it to run on Vista or ask them to fix the issues.

            DEP existed before Vista as well. But with Vista, the security has been tightened. I usually am not a Vista fanboy, but with this issue of yours, you cannot blame Vista. It actually is trying to protect you from something that is presumably malicious.

                  i agree, but when it tells me im not allowed to put an app in the exception list without even a reason, thats not cool.

                                      i agree, but when it tells me im not allowed to put an app in the exception list without even a reason, thats not cool.

                                      Your program is probably marked as /NXCOMPAT[^] (compatible with DEP, the C# compiler does this by default[^]). You can't blame Vista if your program says "I'm fine with DEP" and then isn't.

                                        no, but i can blame vista for giving me ambiguous error messages that make no sense.

                                          Hey guys As some of you might know I've been having issues with Vista not executing a program i wrote, i finally found a work around to that problem, but now Vista is pulling some new stunts! As soon as my app calls the an external DLL(it contains methods to connect and communicate with an external device) the program crashes! I little vista bubble pops up saying "To help protect your computer Data Execution Prevention has closed [program name], click here to learn more." So i click it and find that there is an exception list i can add my app to, i select my app to add it to the list and im greeted with a message box that says "This program must run with Data Execution Prevention (DEP) enabled. You cannot turn off DEP for this program" I dont know anymore, this is really frustrating. :sigh: Does anyone have some suggestions for me? maybe turn DEP off completely? Thanx

                                          fixing your code is a better option than telling your client to turn off DEP. What if their IT won't let them ?
