sometimes when playing oblivion I get a random crash, when it happens I get a message in the bottom right hand corner of my screen saying windows stopped data execution to prevent damage. The thing is that I have already added Oblivion.exe to the DEP exceptions list, but I can't add obse because I have the steam version and it's a dll. anyone know of a solution to disabling DEP on my whole Oblivion folder?

Bump

I recall trying to turn off DEP altogether a while back and according to the cmd shell method it is off.

yet on recent Oblivion Crashes I'm notified that it is still active.

Even logging on as Admin I get no option to edit the DEP list.

What ... do ... I ... do?

I don't think I've ever seen an actual DEP notification. What's it look like? I currently have DEP set to only protect Windows processes and that seems to do just fine.

The notice pops up in the notification area - only for a few seconds saying that DEP closed oblivion. Not sure where to find a log about its actions.

But I know I turned DEP off via cmd shell commands. I double checked and it is off according to a double check using said cmd shell. http://www.addictivetips.com/windows-tips/what-is-data-execution-prevention-dep-and-how-to-disable-it-in-windows-vista/

I'm on Vista.

Frustrating. I think I will turn it back on then see if can get it to exclude Oblivion and OBSE and hopefully not get the issue that Lord Dagon got.

No - this is strange.

Reactivated DEP and set it only to monitor the operating system - still when Oblivion crashes I get notice that DEP closed it.

WTH.

Sounds like Oblivion may actually be trying to execute in areas the OS really doesn't want it touching then.

Hmm I just had a crash that didn't result in that message.

thinking ... thinking.

Is it that this message is generic spam that windows sometimes gives in absence of real info ... or is this an indication of a difference in crashes? Like if one crash is system overload and I don't get the message and another is script error/conflict and I do. Or vice versa. maybe the message stopped now that I changed DEP? Or not.

Darn thinking ... now I have a headache.

Just need to track it more.

My lite stone to the garden.
Win7 . I was trying turn off DEP at all via bcdedit . I did it . I checked out the thing in task manager. The result made me being disappointed - part of the process was under DEP still.
Conclusion: Task manager lying , or uncle Bill cars about us behind our back.

What's it called in task manager? Because now I have it on and I don't see a bdcedit.exe in task manager.

http://www.sevenforums.com/tutorials/2676-bcdedit-how-use.html . In task(s) manager you may see (in theory) the effect of your work (view/chose columns).

P.S.
I have Polish windows, so the terms I used might not fit English one directly.

Hmm I don't consider the cmd shell as part of the http://www.sevenforums.com/general-discussion/2265-windows-task-manager.html. I turned it off then on in the cmd shell but with either I've yet to see it come up in the applications, processes, or services tab of task manager under bcdedit.exe or DEP or Data Execution ... which makes me think it has a different name ... or it is not something that the task manager tracks.

We can't understand each other . It must be I used your language some bad way (not first time).
1. bcdedit is the tool allows you to edit bootlog.ini (or something ) file by some commands typing . You can turn off DEP at all this way.
2. In Task manager you can see DEP status of each process is running . You should just change option of "View" toolbar.

P.S.
Do you remember I raved something about "buffered ram" and PCB ? It is just "cashed ram" in English win version.

Turning off DEP for your entire system is probably not a good idea. If you're setting Oblivion.exe as a DEP-excluded process, that is enough to exclude OBSE as well as we run in the same address space. Generally, though, if you're seeing crashes that are being reported as DEP violations, it was going to crash anyway unless you have a badly written OBSE extension DLL.

DEP = Data Execution Prevention, or putting it in a way easier to understand, preventing areas of data from being executed as code. We don't dynamically generate executable code, neither does Oblivion, so anything hitting DEP is just a crash from another piece of code jumping to an improper location in the middle of data.

Well it is back on.

So what your saying is that when I see some crashes that give the notice and some that do not there is not a correlation between what kind of crashes and the appearance of he message?


wkomarecki-
Is DEP in the task manager seen as a row or a column?

This is additional1111column1111One111row==one111process111.My111keyboard111is111broken111to11see

The situation is over control, I suppose. have you get it ?

The main message I'm trying to give is that any crashes that show the DEP notice are going to crash the game no matter whether or not DEP is enabled.

edit: The message is there as a backwards compatibility thing - some applications assumed that all allocated memory was executable. These programs need to be added to the DEP exclusion list to run. However, the message logic can't tell if the application intended to execute data as code, or if it's just crashing and happens to execute data as code while in the middle of crashing.

Well the mystery for me was why was I still getting the message when I had DEP off.

Now it seems what you are telling me is that the message itself is near meaningless.

Is Bill Gates a descendent of Franz Kafka?

I still don't understand if that means you find it running in a column (globally) or in a row (as one process).

Exactly the same way you can see info about PID of process.
You ask me column or row . But a column is just collection of rows. both Jaroslav Hashek and Franz Kafka are smiling over our conversation. I will link some screenshot when I beck from work ( if necessary ).

In task manager there is File, Options, View and Help. Click on View and then something along the lines of Select Columns... (I have a Dutch version of Windows). You can select which columns you want task manager to show. One of them is DEP.

There it is - thanks.

It was a column.

You're welcome!

Protect and serve, it's what we do :laugh:

Glad you get it . Sad a bit I can't explain even such easy thing. Never mind.
If you are toying this DEP setup, may you tell me what the case, pointed in #8 post of this topic by me, looks in your system ?

oh hey my thread was bumped, good timing because now I'm periodically crashing because of DEP but now I'm learning that the message is meaningless since Oblivion was going to crashing anyways and turning DEP off is useless?

It's meaningful to let you know that you might have an application that dynamically generates code, but doesn't mark the memory used to store that code as executable. Other than that... not so much.


Yes. Leave DEP on, it's a useful security feature.
