Some Windows users report that they get “AAE Error -6117” when they try to download Pro Tools. Other users report seeing this message when they try to open the PlayBack Engine menu (by pressing the N button on the Start screen).

This error code basically means that the audio device cannot be initialized. In most cases this problem occurs because there is no driver for the interface you are trying to use.

The first thing to try to solve this particular problem is to force the PlayBack Engine window to start immediately after starting the Pro Tools application. In most cases this helps to avoid potential conflict between the recording or playback device and Pro Tools.

It turns out that this problem may also occur if you miss the required audio interface driver. In this case you can either install it from the official AVID interface download page, or (if the driver for your model is unavailable) replace the official interface driver with the ASIO4All driver.

If an AAE 6117 error occurs when opening Pro Tools | First of all, you can do it in Windows using Pro Tools | First of all, the interface driver is unavailable because it is used by another application / process. We have seen cases when Pro Tools | First of all, it can get stuck in this state.

This problem should not occur with Pro Tools First 12.8.2 or newer. If you are using an earlier version of Pro Tools First, update it from your Avid account (download the updated installer from My Products and Subscriptions) or update the Avid Applications Manager (Start / Windows Icon> All Applications> Avid> Avid Application Manager).


If this problem still occurs with Pro Tools First version 12.8.2 or later, try the following first:

  • Close Pro Tools | First
  • Go to Control Panel> Sound. Disable all devices in the “Playback and recording” section.
  • Install ASIO4ALL: (this is not required to run Scarlett, but if another ASIO driver is present, Pro Tools | First can be removed from this state).
  • Disconnect Scarlett from your computer.
  • Start Pro Tools | Again. Now you can open it and select the ASIO4ALL driver.
  • Create a session and close Pro Tools | completely first.
  • Connect Scarlett to your computer again.
  • Open Pro Tools | again.
  • After loading the session, go to “Setup”> “Playback mechanism”> and select the Focusrite driver.

Install the device driver

This error means that “the device does not exist” and is most likely due to the lack of a driver for your interface.

  1. Download and install the driver for your audio interface (drivers for Avid interfaces are available at
  2. If the driver is not available or uses built-in audio hardware on your PC, install ASIO4ALL.
  3. Immediately after starting, press and hold the N button until the Playback Engine window opens to select your device.
