Novation's Components software runs in a web browser using the Web MIDI API. This feature is currently only available on Windows, Mac, and Linux in Chromium browsers like Google Chrome (version 50 or later), Microsoft Edge, Brave, etc or in Opera.
To resolve this install the latest version of the supported browsers on your computer.
Alternatively, you can use the standalone version of Components available from the Downloads & Activation Codes tab after registering your product in your account which runs on Mac and Windows.
