Here we addresses common iZotope product authorization errors and solutions, including "Invalid Serial" caused by extra spaces or incorrect entry, "License Not Found," and reaching the 5-time authorization limit. It explains issues like serial numbers linked to another account, mismatched product serials, and iLok authorization restrictions. Connection errors often stem from firewall or antivirus blocks, with offline authorization recommended for legacy products. Links to detailed support articles and account purchase history are provided.
After purchasing and installing iZotope products, there are occasional errors you may run into. Here are some common authorization issues and how to resolve them!
Invalid Serial Error...
The most common reason this occurs is if you accidentally add a space to the beginning or end of your serial number when entering it into the authorizer window. To be sure, please click on the end of your serial number after it has been entered into the authorization window and press the delete key a few times to remove any unwanted spaces.
Please also ensure that you have entered the serial number correctly. Your unique iZotope serial number will begin with an “SN” and follow this pattern:
SN-[PRODUCTID]-XXXX-XXXX-XXXX-XXXX

This serial is in use by another account...

This serial number belongs to a different application...

iLok authorization is not available for this product...
Some of our products, like Vinyl, don't allow iLok authorization. Please authorize with your serial number on your computer.
If your product does allow iLok authorization and you still receive this error, please open iLok License Manager and find your license under the "available" tab. You can drag it to your iLok USB icon from here. If you don't have a physical iLok USB, iLok authorization will not work.
For additional iLok authorization troubleshooting, you can head to the iLok authorization article.
Unable to connect to the license server...
If you're seeing this error with our current product line, it's likely due to a Firewall or Antivirus blocking the outgoing signal. Please check any relevant software you have for the quarantined files or connections.
If you're seeing this with a very old legacy product, please use Offline Authorization as these servers are no longer active.
