Dear @Olympic260,
I just received the same message and never run into this to be honest. I am running one installation on my desktop and wanted to install another on my laptop. On my laptop I installed FSX-SE because of ease of use (nice work on that one!) and am planning to do the same for my desktop. Does PMDG differentiate between FSX-SE and regular FSX licenses? If so is there a way to reset the counter I would like to run FSX-SE on both laptop and desktop.
thanks in advance for your time.
kind regards,
Maurits
