A guide to usage assistance and more
How do I get a new registration code with my upgrade?
You can download the latest version from our Official Website http://www.autodwg.com/ and reinstall the software, you don't have to pay again.
After you update the product to a new version, if it does not ask you for a new code, then it is already registered for you.
If you are asked for renewal the license, you should purchase it via the guide, or you could contact us for the renewal.
