# This is a rather advanced little launcher.
# It runs the program, as requested, but also checks to see if Conda is set up properly.
# It also handles Python errors, assuming a module is not found (didn't install properly) it tries again.
# NOTE: This can't automatically re-run the one-line installer command as that usually requires admin.
