Besides what Owen suggested, you could also use a trick like
multiprocessing does with its freeze_support() function [1]. In that case,
you'd launch your subprocess using sys.executable, like when running
unfrozen, but as your application starts up, check for a particular command
line argument, which tells it to do something other than launching your
application. In your case, that would be running the third party Python
script.
This is also something where my alternative tool, Pynsist [2], might be
easier. Because it doesn't freeze your code, sys.executable points to a
regular Python interpreter, and you don't need any special handling to run
a Python subprocess.
