Rectification : cette fois, Kalypso a fait son job.
Voici leur réponse et le patch à installer.
Dear customer,
The boxed retail versions of Tropico 5 using Kalypso Launcher have been hit by a hideous activation bug which prevents the Launcher from starting up properly.
If you're affected, please download and install a hotfix restoring Launcher functionality from this location:
http://download.kalypsomedia.com/KalypsoTropico5Hotfix.exe
The Fix will auto-install in the correct installation folder for Tropico 5 and the Launcher will then prompt you for any other available updates.
Sorry for the inconvenience!
Best regards,
