Avid Pro Tools – Initializing AAX 64 for Windows
FireWire, Thunderbolt & USB

Important: To use Pro Tools 11 or Pro Tools 12 with UAD AAX 64 plug-ins under Windows, the following steps are required. The procedure must be performed each time an updated version of UAD software is installed (once for UAD v8.5, once for future UAD releases, etc).

Note: These steps are not required when running Windows 10 May 2019 Update (version 1903) or higher.

1. Install the latest UAD software. Be sure to restart the computer after installation.

2. Open the Pro Tools program. The UAD AAX 64 plug-ins are automatically scanned during launch.

3. Click "NO" when Pro Tools displays a message indicating some UAD AAX plug-ins failed to load. This message can be safely dismissed.

4. After all plug-in scans are complete, CLOSE Pro Tools. The UAD AAX 64 plug-ins are now properly initialized and ready for use the next time Pro Tools is opened.

Note: If Pro Tools is not quit after the initial plug-in scan, Pro Tools AAE error -14018, “Unable to locate hardware” and/or other anomalies may occur.
