If your Revoice Pro 4 iLok license is correctly activated on an iLok 2 or iLok 3 USB dongle, or in the iLok Cloud
(and this article will help you check if it really is)
but Revoice Pro 4 still prompts for authorisation at launch, please check for iLok License Manager software updates.
Your Activation Code is designed to work only once - it will not be accepted again.
An outdated version of iLok License Manager software is the most common cause of authorisation problems with Revoice Pro 4.
macOS: Go to the iLok License Manager menu and choose Check for Application Updates...
Windows: Go to the Help menu and choose Check for Application Updates...
- A computer restart is recommended after the installation
