Attempt to implement a shell=False model that hopefully will properly address running on different platform without "fine not found" issues like some users had reported in the past.

When shell=False, we should use a sequence instead of a string. This is because it behaves differently on different platforms, and using a sequence should work on both Windows and Linux.

For a complete explanation, please refer to the python documentation:

I have extracted the key points as follows:

args should be a sequence of program arguments or else a single string or path-like object. By default, the program to execute is the first item in args if args is a sequence. If args is a string, the interpretation is platform-dependent and described below. See the shell and executable arguments for additional differences from the default behavior.
Unless otherwise stated, it is recommended to pass args as a sequence.

On POSIX, if args is a string, the string is interpreted as the name or path of the program to execute.
However, this can only be done if not passing arguments to the program.

On Windows, if args is a sequence, it will be converted to a string in a manner described in Converting an argument sequence to a string on Windows. This is because the underlying CreateProcess() operates on strings.
