AVOX 4.2 uses computer-based Wibu licenses, and not iLok. If you're updating from an earlier version of AVOX that uses iLok, please see this article for important compatibility information. 

If you currently own an iLok License for AVOX 4, Auto-Tune Pro Vocal Studio, or any of the individual 64-bit AVOX plug-ins, log in to your Antares account and go to Upgrades to redeem your free upgrade.

Once you've redeemed your upgrade offer, you're ready to install the software and activate your license:

1.Download and install the WIBU CodeMeter User Runtime application.

2. Download and run the latest AVOX 4 installer. If you don't own the whole AVOX bundle, use the Custom Install option to install only the plug-ins that you own.

3. Open Antares Central (located in the Applications/Antares Audio Technologies folder on Mac, and in the Program Files folder on Windows)

4.Login to your Antares account with Antares Central

5.Select “Manage Licenses” and click Next

6.Click on your Auto-Tune Pro license to activate it.

7. Open the AVOX plug-ins in your DAW and enjoy!
