I have a problem with the setup of KUKA Sim Pro 2.2. It's a network license, I've followed all the steps and acquired the activation file from the visual components website, when I try to start the program and load the downloaded license file (.dat) from the website, it gives me an error that says "Internal licensing system error occured, error code 165". I've tried to search the manuals for this error but with no use. Can anyone help me with this? thanks.
