how do i get the my GMT license

You mean trial version? When you download the evaluation version you can request a trail key and that will be sent to you email address or you can contact the sales team to give you one. Usually they respond pretty quick.

Visit this link you need to create a id/password and register first.

no i have GTM for client and i need permanent LIC, i need to know how ti get the LIC file to be uploaded into boxes

Do you purchase the registration key? If you have the key then you can activate the GTM online - if your devices have internet connection or manually by generating a dossier and going to this link to get the license file.
