Because VetDAR is licensed per computer, activation of VetDAR is a two step process. During installation you will be asked to provide the Clinic/Hospital name which the license belongs to and the Serial Number and Maintenance Plan provided on your invoice. This verifies that you in fact own a license for VetDAR and will allow you to install the software.
When you run VetDAR for the first time, you will be prompted to the activate the license on that specific computer. This ensures VetDAR is not being installed on more computers than licenses have been purchased for. If additional licenses are needed, they may be purchased.
