Rhino 7 license license

My Mcneel Rhino 7 90 days of license will expire within 3 days.
How can I continue right after that ?

You will be able to use that version to view and even work on any files you have previously saved but will no longer be able to save any modifications you have made. Therefore you must make sure you have saved anything you wish to keep before the expiration.

If you have a licensed earlier version of Rhino to use make sure that when you save from the version 7 evaluation that you save the files in the appropriate format for that version.

The only way to continue working on and saving version 7 files is to purchase a license for Rhino 7 as either a full license or as an upgrade from a previous licensed version. If you qualify for a student price it will cost less but have the same functionality as the full version.
