You can tie your IzoT CT and IzoT Net Server Activation Key licenses to a Software Downloads Account.
This allows you to associate all Activation licenses to a specific email account. You can then return or recover activation key licenses.
DO NOT use do a Validation on licenses as that does not work.
You must first have a Software Downloads Account (this server is no longer used for downloads, it is only used for the Echelon License Wizard).
