You have tried to activate a license for a desktop tool and received the error "Failed to activate the license: All entitlements have been claimed". This article explains why this can occur during online or offline activation.
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.
Are other people using the entitlements?
As a 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 purchase more entitlements but if there's 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.
