When you say "key" is that a number sequence you can write down and keep, like a serial number? Seems like the time to switch to Embrilliance-easy to use, inexpensive and as long as you know the serial number you can use it on multiple computers. Hugs. Nan
As the key for Embird is sent by email, I copy the code to a USBstick, where I also save the keys for the different extra parts.
I am not very consistent saving the program itself (certainly not the outdated versions ) as you can always DL the current one.
And that is where the problem starts. Upgrading is not expensive, but the newer versions won't run on Vista. And the older versions are no longer available.
I posted what I do in that post you are referring to.
Please may I suggest that you add which digitising softwear that you are asking about to get the answers you require?
