This may help... personally, I would try #1 and #7 before attempting any of the other solutions.

If you are going to try updating your drivers, make sure to do so correctly and not just install on top of the old drivers. If you have Nvidia, make sure you uninstall the drivers and the PhsyX drivers as well.

Cause of Ntdll.dll Errors

The causes of ntdll.dll error messages can vary greatly. However, most ntdll.dll errors result from a corrupt or damaged version of the ntdll.dll file itself, corrupt hardware drivers, or issues between Windows and other programs. Ntdll.dll errors can sometimes mean that a piece of hardware in your computer is malfunctioning, but this is rare.
How To Fix Ntdll.dll Errors

1. Restart your computer. The ntdll.dll error you're receiving could be due to a one-time, temporary issue and a simple reboot may resolve the problem completely.
2. Reinstall the program if the ntdll.dll error only displays when you use a specific program.
   
   If the software program has any updates or service packs available, install them too. The software's programmers may have identified an issue with the program that caused the ntdll.dll error and then issued a patch for it.
   
   Note: Third party software programs that have been installed on your computer are almost always the cause of ntdll.dll errors. The remainder of these troubleshooting steps resolve ntdll.dll issues only rarely.
3. Check the Windows service pack level you're running and then check Microsoft's support site to see if there is a more recent service pack available for installation. Some issues that caused ntdll.dll errors have been corrected in these service packs from Microsoft.
4. Selectively disable Internet Explorer add-ons. If your ntdll.dll error is displaying when you start, run, or close Internet Explorer, an add-on may be causing the problem. Disabling each add-on, one by one, will determine which add-on is the culprit (if any).
   
   Note: As a workaround, assuming the ntdll.dll error really is Internet Explorer related, install and use a competing browser like Firefox.
5. Rename the NLSPATH system variable. If your Windows system does not have this environment variable, skip this step.
   
   Note: This is a troubleshooting step for this issue only. Be sure to set this path back to its original name if this does not resolve the ntdll.dll issue.
6. Disable Data Execution Prevention for Explorer.exe. As in the previous step, this is for troubleshooting the ntdll.dll issue only. If this doesn't resolve the problem, return the Data Execution Prevention settings to their previous settings.
7. Update drivers for any hardware in your computer where updated drivers are available. Outdated drivers sometimes cause ntdll.dll errors.
8. Test your memory for damage. If you're receiving ntdll.dll messages, one possible cause could be a bad memory module in your system. Testing your memory will either identify a problem or clear your RAM of any responsibility.

Welcome to Seven Forums rorre. I'm assuming your aren't actually having BSOD, but rather just a problem with Zoo Tycoon? Have a look at this KB article for possible fixes.

Game crashes or closes unexpectedly

Make sure you meet the minimum requirements for ZT

1. Tried that, didn't work.
2. For some reason I can't uninstall it any more.. I also can't install updates to the game because it says I don't have ti installed.
3. My Service Pack is up to date.
4. I am using firefox.
5. Could only find this on XP. I have Win7.
6. I tried that, it didn't work.
7. Didn't work.. Sadly.
8. I don't trust doing that.

Any other suggestions?

 

[rorre]

I'm sorry, these didn't seem to help me. I'm pretty sure the computer meets the maximum requirements, the game ran before. It just stopped running now. I tried updating my drivers, and running it on a new profile.
Nothing is working. I would love more help on this if anyone is willing, thanks.

P.S I upgraded my graphics card, would this cause a problem?

 

[AstaLaVista]

Nope, I would try to see if I can download a new/fresh .dll file and get rid of the old but that's about it.

That or revert back to a system restore date before the installation of the game

 

[ShamrockRig]

ntdll.dll free download - DLL-files.com Click on the download zip file button, copy and paste the file inside the rar into the directory

 

[rorre]

Believe it or not, I already tried that. When I try to extract the .dll to System32 it says access is denied.
I went searching to see if I could gain access to System32, but I read that if you gain access to it, it causes problems in the computer. I could try system restore, but I would have to back up a lot of files. Which would take awhile. I decided that was my last resort.
Thank you guys for the help.

Hi rorre,

check this link.

Might help you.

 

[AstaLaVista]

Back up a lot of files? system restore will only interfere with software you have installed and not DATA you have saved per say.

I am not in the habit of copy/pasting files to Windows\System32 either but, once in a while you just have... this is one of those occasions when you have to. You may also have to paste it into the SysWow64 if you are running a 64bit (but I am definitely not sure of this last step). Of course you have to set permissions to the Windows folder before you can paste them.

 

[rorre]

Okay, so system restore will only mess with the games and such I loaded? Because I have some stuff in documents, and downloads that I would like to keep. If so I will probably do it immediately, and get this friggin thing over with.
Best regards!

Again, System Restore does not touch your data... read below (from Microsoft's Website)

Sometimes installing a program or driver can make Windows run slowly or unpredictably. System Restore can return your PC's system files and programs to a time when everything was working fine, potentially preventing hours of troubleshooting headaches. It won't affect your documents, pictures, or other data.

 

[rorre]

Well, shoot. Just restored the computer to the one that was farthest back, and it didn't fix it. Is there a way I can restore it back farther than my farthest restore point? Or do I have to return the system to factory default? If not, would you mind telling me how to put the ntdll.dll into System32?
I appreciate the help.

 

[rorre]

I did all of those except for the data check. None of them did the trick, sadly.

 

[AstaLaVista]

Before going for the ntdll.dll file, have you installed the game again and patched it to the newest version?

Normally I would say that the .dll files are under windows\system32 but after doing a search on my PC I see that I have a few ntdll.dll files and not all point to the same location so, No... I am not going to tell you how to put it because I have never done it before and I don't want to be responsible.

Now, what I can tell you, and at your own risk, is that... normally, all you do is download a fresh copy of the file in question and you copy/paste it to your Windows\System32 location... some other times, you also want to copy it to System\SysWOW64.

Warning... Again, at your own risk!

Hey, I just tried running the game on an external disc drive.... And it worked!
So thank you for all the help.

 

[rorre]

This problem has been solved by using an external disc drive.

 

[rorre]

This has been solved by using an external disc drive to run the game.

 

[archer]

Hey, nice to hear that the issue got resolved. Can you also let us know how you did that?

Did you install missing .dll file from external drive?

 

[rorre]

No. (Sorry for the triple post. Didn't know how that happened. )
I just hooked up an external disc drive that we have, and it worked. There must be something wrong with the internal drive. Maybe the sensor is dirty? I'm not sure.. I just updated the driver, so I know it's not that.
