Hi! I need to upgrade my license from 10 to latest version. And by that way I need to know my license number. But in last three years license activated by accound and I can't find message with number. How can I restore my license key for upgrade reasons? Thanks.
The license number can be found on an invoice in PDF form that we sent to a registered email address when you purchased a license. Please note that TeamViewer licenses are account-based and must be logged in to be used in order to use your license.
With regards to the upgrade, you do not need to do anything as your account will be automatically updated once you purchased a subscription license. For more information about subscription licenses, please read this article.
