The easiest way to do this is manually advance your progress bar with each powershell script completion. for example if there are four *ps1 scripts, then completing each represents an additional 25% completion. popen(ps script 1) advance progress meter to 25% popen(ps script 2) advance progress meter to 50% ..... to get anything more sophisticated you have to have the powershell scripts report something back to the main python script but I don't have a feel for how easy/hard that would be. I doubt that the popen call allows much more than waiting for the called script to exit. You could have the power shell scripts keep track of their own progress with a log file or some such and then a thread in your python installer could watch those log files and manually advance your progress meter based on log file entries.
