Hi Martin,
from your screens it seems, you try to use activation key for S32DS for ARM, but you install S32DS for Power Architecture. I know, there was an issue with license keys on our website, but I think, it is fixed. Please try the following steps:
Click download button for S32DE for Power Architecture

Click license keys tab

Now, you should see the following screen with activation ID

If you have any problem with this progress, please write me back and I will try to ensure the fix.
Regards,
Martin
