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: import main main.run() 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 all. 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. -- http://mail.python.org/mailman/listinfo/python-list

The best thing that I can think of is to have your program to use the subprocess or multiprocessing modules to launch a second instance of itself when an update is required. The parent would pass the child any necessary data so the child could continue where the parent left off, have child acknowledge this transaction, and then the parent can exit. Depending on what your program is actually doing this may not be a reasonable solution. Look into os.pipe, multiprocessing.Queue, and subprocess.Popen.communicate. If you have pywin32 extension installed, win32event module contains a number of useful functions for things like creating inter-process events. - Max -- http://mail.python.org/mailman/listinfo/python-list
