Sorry to be a pain, more below:-
"As for your second question, you do not need a Runtime license while you are using the Pro key. The Pro license can be run in Runtime mode so that you can see what your application would look like on a runtime system. So, I would just do that: develop on your laptop using just the Pro key, then when you are ready get a runtime license for the new computer." that was what I was trying to do, using my license key for Pro and registering on line or manually on that second laptop, but it stops me as I have the Pro license key on the first laptop, but I thought that would be ok as I can obviously only run DAQfactory on the laptop that has the USB key inserted?
Good tip about the runtime license when I install that.
