Running a simple python app on Windows 7 embedded gives an "Entry point not found error" and an "Error loading dll"

Question

I am trying to run a simple small app I made in python on a device running Windows 7 embedded (2GB RAM, Intel Atom). I am creating an exe using pyinstaller (dev version, for supporting Python 3.6)

When I run the exe I get the following error:

the procedure entry point ucrtbase.terminate api-ms-win-crt-runtime-l1-1-0.dll

Followed by this error:

"Error loading Python DLL:
C:\Users\User\AppData\Local\Temp\_MEI57202\python36.dll (error code 127)"

I used pyinstaller as follows: pyinstaller -w -F

Any help will be greatly appreciated.

Thank you.

Please let me know if you need to see the script, it's a simple one.

Edit: Installing KB2999226 from Microsoft did make the error's disappear but now the script will silently not execute.

Any ideas?

Final Edit: Installing the above update solved it. The problem with not executing was I used a 64Bit FFMPEG on a 32bit OS. Closing with solution
