Hi there,
I'm having the same problem with a newly registered licence. The registration file was generated on 23 December for MC17, directly on your website, and i can't get it to work with a portable installation of v17.00.60.
By double-clicking on this registration file, or trying to load it directly from the MC nag screen, it gives me an error 21.
I've try to delete the Licence.dat file inside the application folder, then load the registration file using the 2 methods describe above, and this time it gives me an error 22. Both are qualified as "unknown error"
I can't launch the automated installation process using the MediaCenter170060.exe on my development machine since it's an embedded platform. The application has to be portable in order to work, or being implemented as a component during the Target Designer stage of Windows Embedded.
So what can i do in order to use the application i've paid for?
Also, another question : does your registration process include a "call-home" procedure, or if you prefer, is it necessary to be connected to the Internet in order to register MC using the .mjr licence file?
Thank you in advance for your answer.
