Turboactivate fails as a non-privileged user with error code 15.Locked

We are using a product called Arrow Teaching Technology at our school. Students do not have admin rights. When they click on the Arrow Teaching icon, Turboactivate comes back immediately with error code 15. I am assuming this is to do with permissions as it works fine and activates the software when I login as an admin user. What is it trying to do?Thanks.PHHS Technician

Contact the company that makes the product (that's not us). There are thousands of reasons why an error might happen it most of them depend on how they use our products.
