Hello,
I checked your account. It seems this license is setup to work for both S32 Design Studio 3.4 and 3.5. I also see you only have one license. If you would like to have 100 licenses, you can entitle your account for a S32DS 3.5-only license here:

Otherwise, you could select Yes on that dialog window and then try to activate again and it should work.
Best Regards,
Mike
