If your Sonnox plug‑in doesn’t appear in your DAW after installation, it may have been blocklisted or skipped during the DAW’s plug‑in scan.
This can happen if:
The plug‑in wasn’t activated to a valid iLok location before opening your DAW.
You ran the installer while your DAW was still open.
Your DAW detected a connection or licence issue and marked the plug‑in as “faulty.”
This guide walks you through checking your installation, licence activation, and re‑scanning your plug‑ins.
Prerequisites
Latest Sonnox plug‑in installer (download here).
Latest iLok License Manager installed (download here).
Valid Sonnox licence in your iLok account.
Correct DAW plug‑in scan paths set.
Step‑by‑Step Solution
Close All DAWs
Make sure no DAW is running before making changes.
Open iLok License Manager
Sign in to your iLok account.
Check you’re signed into the correct account if you have more than one.
Check Your iLok
If using USB, plug it in and confirm it appears in the left panel.
If using iLok Cloud, go to File → Open Cloud Session.
Confirm Your Licence is Activated
Your Sonnox licence must be activated to your iLok USB, your computer (Machine Authorisation), or Cloud.
If not, drag it from your account onto the correct location.
Synchronise Your iLok (USB only)
Right‑click your iLok and choose Synchronise.
Check Plug‑in Installation Location
Ensure the plug‑ins are installed in your DAW’s default plug‑in folders.
Confirm your DAW is set to scan these folders.
Re‑Scan Plug‑ins in Your DAW
Most DAWs allow you to clear the plug‑in cache and force a rescan.
See DAW‑specific instructions below.

FAQ / Common Questions
