Validate License


I have recently uninstalled and install Rhino 5 again, however there’s always a popup to remind on the validation. I have changed my email address before. How can I activate the validation successfully?

So, nothing happens when you punch the “Validate Now” button?

Yes I have tried and followed with a “Next” button. Please see below :



As the screen says you used a different e-mail address on the previous validation. You can only use one address, it will not accept a second one. If you don’t remember the validation address or need to change it, contact directly.
