Question
cannot acivate with a licensed key file.
Trying to Activate with the Key file that you emailed me, but it will do nothing after browsing to the license key location on my computer. I selected the product to be activate and all I have is the screen that says Done, the following products has been licensed (PTC Mathcad Prime 6.0.0.0), and my only choice is to Exit.
if I do Exit, it still says 28 days left or less days.
