Install SWB Audio Capture

If you want to record system audio with iShowU Instant, you first need to install a driver.

The driver is bundled with the app. Here's how you do it:

1. Open iShowU Instant
2. Go to Audio Tab (I'm showing you the 'Advanced' view, but this button appears in both Basic & Advanced)
3. Click 'Install SWB Audio Capture'
4. Enter your credentials
5. Done!

You know it's complete when the app changes, and that "Install..." button is no longer showing.
