To answer your questions,
1. Vectric do allow license transfers. We need to contact the original owner to verify the position and to cancel their original license, so a new license can be issued to the new owner. There's a $50 charge to cover the administration costs associated with validating and transferring a license.
2. The Trial version will allow you to save toolpaths for the Evaluation files supplied with the software so these can be run / tested on your own CNC machine.
The Trial versions of the Vectric software products will open your own designs, calculate and preview toolpaths, but not allow these to be saved as CNC code.
Files created and saved using the Trial version cannot be opened on another PC using a full version of the software. This means you can't design using the trial version and send the file to a licensed user to obtain the toolpath code.
