Resolution
The ntdll.dll file can cause this error for a number of reasons. Try each of the following resolution options and re-test after each. If the error persists, move to the next step, try and re-test. Continue this process until the error resolves or when you get to the last step.
- Restart your computer. The ntdll.dll error you received could be due to a one-time, temporary issue and a reboot may resolve the problem completely.

If this does not resolve the issue re-enable Data Execution Prevention - Disable UAC.
