transferring existing subscription to new device

Hi @nedesigns, 

Welcome to Trend Micro Home Users Community.

If you only have a 1 seat license, the registered device cannot be removed.

To work around this you could to the following:

1. Install Trend Micro on the device you want to be protected
2. During the activation, you'll get a message "Too Many Installation"
3. Enter your Trend Micro Account credentials to sign in to your Account
4. Choose the old device you want to remove Trend Micro from
5. The activation should continue and the new device will be protected

Hope this helps!
