PyInstaller cannot parse "HMODULE WINAPI LoadLibraryExW(LPCTSTR lpFileName, HANDLE hFile, DWORD dwFlags);"

[Chuck Recker]

I'm trying to make a 1 python file executable.  I'm using the command:

> pyinstaller -- -w My_program.py

and I'm getting the error:

Am I missing a DLL or something?

Thanks,

Chuck
