pyinstaller exe won't close

Question

I have problems with all exe files created by pyInstaller. It's reproduceable in a simple hello world example written in python 2.7 that runs in the console. The problem is that the script runs (seems to run ok), but after the execution the "parent" shell (the cmd where I ran the exe from) dies and nothing short of a reboot of the pc will close it (cmd or total commander both).

So the parent thread just hangs running my exe's. I am wondering if I have botched the install of pyInstaller or pywin32 somehow, used the wrong version etc? Also, once I made the exe with an error in the script, the exe ran and exited with the typical python debug print (but the parent script did NOT hang this time).

Edit: I have since reinstalled python, easy-installer, pywin32, pyinstaller and still have the same problem. I downloaded everything in x86 version this time around from the following url's (was links but need 10 rep to post):

Python, ez-setup link here, Pywin32, PyInstaller link here

The script is just a simple:

print "Hello World"

The pyInstaller output when building the exe:

My system is a i5 (64 bit) Windows 7.

Answer 1

I do not fathom how I could miss it, but its simply my Avast antivirus program interfering. One of the shields was causing all my python exe's to "stall" its calling parent window upon completion.

Answer 2

If you're having problems then try to re-install the program. Or try to download a more recent version of Python.
