You have tried to activate a license for a desktop tool and received the error "Failed to activate the license: All of the x entitlements for serial xxx-xxx-xxxxxx-xxxx have already been claimed". This article explains why this can occur during online or manual license activation.
1. Are you logged in?
You will see this error if you're trying to activate a license and are not logged in. On the toolbar, click on Help > Manage license to check. If not, log in with your Redgate ID.
If you log in with the same Redgate ID each time, then you will be able to activate on as many machines as you need without running out of entitlements.
2. Are other people using the entitlements?
As license owner or admin you can check to see if anyone else is using the license by visiting the Users tab of the Redgate licensing portal (portal.red-gate.com). If you can't see any licenses on this page, you'll have to ask the owner to do this, or request that they add you as an owner or admin.
It may be that you need to buy more entitlements but if there are users registered on the license who no longer need it, they can be removed. Similarly, if you or someone else has recently changed email address or have used the same license from different email addresses, then each different address will consume an entitlement. Remove the old addresses to free up entitlements.

3. Are you doing a manual activation?
You may encounter this error when trying to manually activate a license on a machine without an internet connection.
You're not prompted to log in with your Redgate ID when you manually activate so the licensing server counts the activation as an additional entitlement and displays as Device: (xxxx-xxxx-xxxx-xxxx) in the customer portal.
You'll need to ask the license owner to remove you as a user in the portal (thus freeing up an entitlement), and then perform the manual activation. When you go to activate the license again, remember to remove the 'Device: xxxx' user in the portal, or ask the license owner to do it, to free up that entitlement.
