From the Help|About section or from the documentation, you should be able to get the required contact information.
It could be a telephone number or an e-mail address.
Contact them with the code. They'll give you the registration key.
NOBODY but Mico can give you a valid registration key, as each one is specific to a single installation. The code is globally unique.
