Pyinstaller exe APPCRASH Error with ntdll.dll in .exe on Windows 7

Question

I have used pyinstaller to make the exe file. I am experiencing an issue with an application on Windows 7, and I need some help diagnosing the problem.

The application is DataPilotSetup.exe (version 1.0.0.0), and it crashes on startup with an APPCRASH error. The faulting module according to the problem details is ntdll.dll.

Here are the problem details:
Problem signature:
  Problem Event Name: APPCRASH

On my other windows 7 system the error showed up as missing api-ms-win-core-path-l1-1-0.dll which i resolved by copypasting them into my system32 & sysWOW64, but it didn't resolve the problem.

This is the pyinstaller command i use --

pyinstaller --hidden-import "numpy.core._dtype_ctypes" --hidden-import "canmatrix.formats" --hidden-import "canmatrix.formats.dbc" --hidden-import "canmatrix.formats.arxml" --hidden-import "asammdf.blocks.cutils" --hidden-import "psutil" --additional-hooks-dir=hooks --onefile --noconsole --splash "C:\Program Files (x86)\IBDS\DataPilot\img\splashscreen.png" --icon "C:/Program Files/Airforce_Application/Airforce/img/ico.ico" --uac-admin --name "DataPilot" python.py

Does anyone have any suggestions for what to try next, or any insights into what might be causing the crash? Any help would be greatly appreciated.
