Grant, If you are building paths in you code that are relative to your app, please see my reply to Greg's post. If not, you may as a workaround want to try to add the frozen application's directory to the system path environment variable. Windows will look for dlls there, too. To get the app's actual location, you will need something like the getAppPrefix() function as per my reply to Greg's reply. The getAppPrefix() function will also hold when the user adds your frozen app to his/her system path and call the app from any location from the command line - sys.argv[0] just won't do the trick in such a setting.

Re: py2exe windows apps path question
If you need something that works both on a frozen app as well as an (unfrozen) python script, you'd be better off using something like: def getAppPrefix(): Return the location the app is running from isFrozen = False try: isFrozen = sys.frozen except AttributeError: pass if isFrozen: appPrefix = os.path.split(sys.executable)[0] else: appPrefix = os.path.split(os.path.abspath(sys.argv[0]))[0] return appPrefix Vincent, This sounds interesting. A few questions for you: Why don't I see sys.frozen in interpreter? Does it only appear when it is frozen? What do you mean by frozen, how does python know? What does sys.executable do?

A few questions for you: Why don't I see sys.frozen in interpreter? Does it only appear when it is frozen? Yes. The sys.frozen attribute is added by py2exe. What do you mean by frozen, how does python know? Python doesn't know - it is just told so ;) What does sys.executable do? sys.executable gives you the path of the executing binary. Normally, this will be something like c:\\python24\\python.exe - since the interpreter is the executing binary. Once you have frozen your python application, it will return the path to your app. -- Vincent Thanks, Greg -- http://mail.python.org/mailman/listinfo/python-list
