Here's what I did, which works really well. The main script imports
other python modules which do the real work of the program. It is
only a few lines long and looks something like this:
There is more stuff there, imports etc to help py2exe find everything,
but that's the basic idea. Then, to upgrade the program, all I have
to do is replace the modules which are in a subfolder. (And be
careful to reload them, which has its own considerations).
I do some wonky stuff in my build script to delete my main modules
from library.zip since its easier to replace them outside of that, you
could also use the skip-archive option to not use the .zip file at
You really can't replace an exe itself while its running, I would
avoid that as much as possible. Workarounds to do this are highly
prone to error.
