To resolve the issue of an Expressive E plugin being listed as "not compatible" in the Logic Pro plugin manager, first ensure that you have the latest version of PACE License Support installed on your Mac. You can download it from www.ilok.com. Alternatively, if iLok License Manager is already installed on your computer, you can also obtain the latest version via its Help menu ("Check for application updates").

Then, please ensure that you have already activated the plugin's license on your computer. If you haven’t had the opportunity to enter the plugin's activation code yet, please activate the license directly from the iLok License Manager application. It’s explained here: Activating your instrument plugin with iLok License Manager

Once you are sure the license has been activated on your computer (or a connected USB dongle) and that License Support is up to date, please reboot your Mac. After the reboot, launch Logic Pro again and open its plugin manager. If the plugin is still listed as "not compatible", select it and click “reset & rescan selection”.
