At then end of the installation on win6.1: Create process failed; code 740 This is probably InnoSetup trying to launch the application it has just installed. The "details" on this error are totally unhelpful. According to the ​InnoSetup documentation, runasoriginaluser is the default when using postinstall. Why you can install software but not run it is beyond me...

When starting the software, it asks every time Do you want to allow the following program from an unknown publisher to make changes to this computer. Maybe this is the logfile we are trying to open? (it obviously does not tell you anything remotely helpful to diagnose) We do not want administrator privileges! Just the ability to write to our own configuration/data files! The information I found uses ​app manifests to gain full administrator privileges... (typical microsoft sledge hammer defeating security) Or maybe it doesn't run asInvoker unless you tell it to? Not according to ​this ​http://stackoverflow.com/questions/195109/running-compiled-python-py2exe-as-administrator-in-vista

The download link for mDNS "Download from apple.com" should popup a browser, but instead you get: The application was unable to start correctly (0xc00000a5). Click OK to close the application. This one may be resolved with the manifest above...

Our app avoids placing an icon in the task bar (window.SKIP_TASKBAR), so windows should get out of the way and let us live in the tray (aka notification area). But no, nanny-microsoft decides they know best, so we would need some code to go and hack the registry (yuk), something like what is mentioned in ​this thread.

Why is it trying to open a path that points to the Desktop where we built the DMG, this path no longer exists (applet.py is in the same location as the other .py files), but it succeeds?? (and fails on importing pygtk...)
