You don't need those two lines.  In fact, they are a bad idea.  Just say "subprocess.Popen" (which is what you are actually doing).

You don't need two sets of quotes here.  The file name does not actually have quotes.

Yes, you need to find the window handle of your dialog.  You can use the FindWindow API to do that.
