while opening the mail i got for license key it says its invalid
Hi @arthut786,
Can you kindly try to login to TeamViewer client with your TeamViewer account then check on License from About TeamViewer (Three lines icon from Top left corner).
If License shows with the correct license type, you have successfully activated the license on your account. Kindly login to your licensed account every time prior connections.
If License shows Free, kindly try the activation steps or contact TeamViewer Support Team for further assistance.
I hope the information would be helpful and if you are experiencing any difficulties, feel free to comment below.
Warm regards,
Ying_Q
