I have an older version of Immerse Virtual Studio| Audio Technica, how can I update?

The updates are issued on the plugin itself. If a new version is available, just close and reopen the plugin; you will see a notification “Software Update Available” on the top right. Go to your user information to click on the update. Click on the link to download the new version of the plugin. Close your host DAW  and run the new installation file. You now have successfully installed the new version of the plugin.
