PTC Customer Agreement
The installer prompts you to accept the license agreement. Acceptance of the license agreement is required for installation. The person installing this software must have the legal authority to accept the license agreement on behalf of the customer. If the installer does not accept the license agreement, instructions appear on-screen with respect to how to return the software for a efund. Note that a refund will only be given if the instructions are followed in a timely manner (no later than 30 days after the software is shipped by PTC). Before you are allowed to accept the agreement, you must scroll all the way through it to acknowledge you have reviewed the information.
