Going around in circles here!
In both MEPP 2016 and MEPP 2017 I no longer have access to the "MPEG-4 FULL Codec Upgrade" I purchased 20 months ago for £3.99.
Placing an MP4 or MOV on the timeline, for example, result in the message:
"The program needs access to a file with MPEG4-Codec. For copyright reasons, activation is
required. Would you like to activate MPEG4-Codec now for free?"
Choosing "Activate onllne"
gave me the message
"Hint
The activation of MPEG-4-Codec failed.
If you are using the program as a guest, please
repeat the activation procedure with
administrator rights."
No idea what the reference to 'guest' means but admin privileges made no difference.
I then used the Support page and received a prompt email with a new activation code. But after applying it and repeating my attempt to start a project it failed in identical manner.
This is similar to those from several users raised in this thread, which I studied:
https://www.magix.info/us/forum/mpeg-4-codec-version-i-purchased-is-not-working--1199559/#ca1362495
but none of the suggestions so far have helped me fix it.
I'm now at a loss and practical help would be much appreciated please.
In particular, what is a fail-safe method to apply or restore an activation, when the codec is already shown as installed?
