What is the advantage other than being able to use more than one
Right now my license was set after a phone call to Bob -cad when I activated the software. Is the dongle worth the extra cash?
If you use more than one computer it is ; ) Also good insurance if you machine crashes. You can rebuild the computer, install BobCAD, and you will be good to go with the Dongle. Without it you will need to call them again and explain the situation, and hope they believe you!
