Problem with opengl32.dll

[Wolfspirit]

First, hi guys I'm new here (although I've been a silent reader for months now ).
Since I followed the Troubleshooting step for step, searching for a mention about problems with the opengl32.dll file and not finding any I set my mind on posting a report.
1. I have tried it with the game versions 1.6 and 1.43 (good thing I had a backup of the setup file)
2. I already searched here and on google
3. the game strangely doesn't create a blackbox.txt this time
4. I have the non steam version (I tried the demo)

So... my problem is, everytime I try to play a game the game crashes with a typical windows error report saying "defcon.exe has encountered a problem and has to be closed..."
looking at the details I found out that there seems to be a problem with the "opengl32" file. Instantly I searched the site "DDL-Files" and downloaded the opengl32 there, put it in the games directory and started the game, but this didn't work either, it also crashed.

So my question is: Has had anbody the same problem and could solve it? If yes please help me with this one.

Before I forget it, I also had problems with my atioglxx.dll file earlier this day, after downloading 5 ATI drivers, unpacking them and putting their atioglxx.dll file into the games directory the game finaly accepted one of them and I at least could open the mainmenu.

Here my crash-report:

Fehlgeschlagene Anwendung defcon.exe, Version 1.0.0.1,
fehlgeschlagenes Modul opengl32.dll, Version 4.0.1381.4,
Fehleradresse 0x0000a61c.

Sorry for it being german, I could also translate it if anybody doesn't understand.

Umm, don't mess with OpenGL.dll. It's part of your graphics card driver, if you just fetch it from somewhere, it's unlikely to match your GPU. Don't copy parts of the ATI driver into the game directory, either, that's asking for trouble every time you update your driver. I'd delete all of the DLLs you put into the game directory and just install a proper, current driver for the graphics card, one fetched from the manufacturer directly and not from Windows Update.

[Wolfspirit]

Nah, I didin't change the OpenGL.dll, but I also downloaded the current ATI driver 10.12 from the manufacturers site. And with the current driver and the dll's in the game directory removed, the game doesn't even start. Every other game does work though. I even use another program with a seperate atioglxx.dll and I had no problems with drivers before and after using that program.

It's just strange, why doesn't DefCon accept the atioglxx.dll and opengl32.dll the driver did install.

I hope you guys can help me further. I just want to play DefCon.

Most other games don't use OpenGL. Maybe try one that definitely does? Shameless plug for mine.

[Wolfspirit]

Nope, doesn't work. It shortly opens but then crashes without a error report or anything.
I'm beginning to believe that my opengl32.dll is wrecked. But thanks for the help anyway.

Yeah, that's what the test was for I don't know what you did with your system, but you must have broken general OpenGL compatibility on the way. Usually, clean driver reinstalls do the trick (completely remove the driver so you're stuck with default VGA crap, then reinstall the latest), but that's about all I know about repairing stuff like that.

ARGH!
It still doesn't work, Armagetron either. I deleted the driver cleaned my drive with DriverCleanerPro (in Safemode) and installed the 10.12 driver (AGP) freshly. I just get to see the world map a second and then it crashes. It's still the old problem with opengl32.dll. Say is there an alternative way to pass the problem, like, downloading OpenGL as complete pack? It's my last resort, if that doesn't work I'll have to delete DefCon (which I don't really want to do). I remember that 2 or 3 years ago the game worked but at that moment I didn't have enough money to buy the full version so I thought that I could try it again this year.

There are standalone OpenGL implementations, but those only offer software rendering. Only your GPU vendor can give you accelerated OpenGL (there is the theoretical possibility of an OpenGL implementation using DirectX as backend, and I think that's what Vista/7 offers). No, you really need to clean up the driver mess; a reinstallation of Windows may be the only way at this point. You strike me as the kind of guy who buys PC magazines with "Speed up Windows with the Registry Cleanup PRO included in our cover CD!" on their title and actually runs those and feels that messing around with system files is a good idea. Well, it's usually not, unless you know exactly what you're doing. Moving around files should be a last resort. You probably just broke OpenGL with a previous action and need to be a little less reckless. Yeah, I'm not helping, sorry. Maybe someone else has a good idea what can be tried at this point?

Tanks guys, I finaly had a first success. I can play the tutorial. But I still can't play the normal game and besides it's running somewhat slow at the moment.
Here are my PC specs:

AMD Athlon XP 2400+ (2.00 Ghz)
ATI Radeon HD 3850 AGP (512 MB)
2x 1024 MB Corsair RAM
Windows XP (SP3)


And the fact that I can play the tutorial proves that my opengl32.dll still works somehow.

@Bert: I got a error report for Armagetron, it says that they game couldn't initialize my video system. Could that be related to the fact I'm using an AGP card?

Nah. It was developed way pack when AGP wasn't even on the map and never had specific AGP problems while that bus was current tech. The error means that no suitable accelerated video mode could be found. Which is odd, it usually plays nice even with software rendering OpenGL implementations.

OK, I finally found the cause of the problem: the chipset drivers for my board seemed to have problems when I installed them. Solution: I cleaned up the ATI drivers, completely reinstalled the chipset drivers and reinstalled the ATI Desktop drivers. It finaly works now, I can at last play DEFCON (without lag).
