Fix 3: Run the Program Compatibility Troubleshooter

This issue may also be triggered by a poor written program. If your program crashes with the ntdll.dll error when opening or closing a program, or just when a program is running, it’s time to run the Program Compatibility Troubleshooter.

The Program Compatibility Troubleshooter can check whether that program is compatible with your current Windows operating system or not. Just follow the steps to run the Program Compatibility Troubleshooter:

5) If the problem persists, adjust the following settings manually and select OK when you’re done.

  • Compatibility mode: If your program is not designed for your current Windows system, the program may crash with the ntdll.dll error. Click the drop-down list to select a previous version of Windows system to test run the program.
  • Run this program as an administrator: If the program is not given administrator privileges, it may not run properly and may even crash with the ntdll.dll error. Try this setting to give the program the administrator privileges.

If this fix works, your program won’t crash with the ntdll.dll error.


Fix 4: Disable the problematic add-ons of your Internet Explorer

If your Internet Explorer often crashes with the ntdll.dll error, this issue is probably caused by the IE add-ons. Try selectively disabling the add-ons of your Internet Explorer one by one until you find the add-on that causes this issue. Here is how to do it:

1) Open your Internet Explorer, then click the gear button to select Manage add-ons.

2) Select the first add-on in the list and then click Disable.

3) Close your Internet Explorer and reopen it to see whether this issue persists. If so, repeat step 2 to disable the rest of your add-ons one by one until you find the add-on that causes this issue.

2) On your keyboard, type the command lines below one by one and press Enter:

Dism /Online /Cleanup-Image /ScanHealth
When you run the command mentioned above, the DISM tool will scan all the system files and compare them with official system files. The function of this command line is to see if the system file on your PC is consistent with its official source or not. This command line doesn’t fix the corruption.
Dism /Online /Cleanup-Image /CheckHealth
When you run the command line Dism /Online /Cleanup-Image /CheckHealth, the DISM tool will check whether your Windows 10 image exists corruptions or not. This command line also doesn’t repair the corrupted files.

It may take several minutes for this command operation to be completed.

3) Close the Command Prompt when the restore operation completed.

See if this issue persists. If so, try running the System File Checker.


Fix 7: Run the System File Checker

The System File Checker can scan for corruptions in Windows system files and restore corrupted files. When this annoying issue appears, it may be caused by some corruption error. In this case, running System File Checker may help you resolve this issue. Here is how to do it:

1) On your keyboard, press the Windows Logo Key and R at the same time to open the Run dialog. Type cmd and then press CtrlShift, and Enter on your keyboard at the same time to run the Command Prompt as administrator. You will be prompted for permission. Click Yes to run the Command Prompt.

Fix 8: Replace the file ntdll.dll from trustworthy source

If your Windows OS is 32-bitthe 32 bit ntdll.dll is inC:\Windows\System32.

3) Based on your system type, copy the file ntdll.dll from another trustworthy computer running the same version and edition of Windows operating system and paste it to your own Windows operating system.

If your Windows OS is 32-bit, paste the new filentdll.dll to C:\Windows\System32.
If your Windows OS is 64-bit, go to C:\Windows\System32 and paste the 64-bit ntdll.dll to C:\Windows\System32 on your PC; then go to C:\Windows\SysWOW64and paste the 32-bit ntdll.dll to C:\Windows\SysWOW64 on your PC.

4) On your keyboard, press the Windows Logo Key and R at the same time to open the Run dialog. Type cmd and then press CtrlShift and Enter on your keyboard at the same time to run the Command Prompt as administrator. You will be prompted for permission. Click Yes to run Command Prompt.

Pro tip: Update your drivers

If there are outdated or missing drivers on your PC, it is a good idea to update your drivers to the latest version, since by doing that, you can avoid many computer issues.

There are two ways to do it: manually and automatically.

Update your sound card driver manually – You can update your drivers manually by going to the manufacturer’s website, and searching for the latest driver for your device.

Be sure to choose the driver that’s compatible with your exact device model and your version of Windows.

Or

Update your drivers automatically – If you don’t have the time, patience or computer skills to update your drivers manually, you can, instead, do it automatically with Driver Easy.

You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. Driver Easy handles it all.

1) Download and install Driver Easy.

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem driver.

3) Click Update next to your device to automatically download the correct version of its driver, then you can install it manually. Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (This requires the Pro version – you’ll be prompted to upgrade when you click Update All. You get full support and a 30-day money back guarantee).

You can do it for free if you like, but it’s partly manual.
