On Windows 7, I'm using WinPython which is the custom Python distribution for scientific programming including many modules and extras (like numpy and matplotlib). I want to use PyAudio, but I'm stuck at running the installer. There's no Python entry in the registry. WinPython is kind of annoying--does a lot of things its own way. The PyAudio installer pops up a page asking me to type the explicit Python location, but the form doesn't accept entry.
