Hi David,
Here's the way to determine if the Adagio Lanpaks got installed correctly. When you open any Adagio application, go to the Help menu and choose About. On this screen the number of users and available Lanpaks are shown.
If you see something like '0 of 5' or '1 of 10' on the screen, that means the Lanpaks got installed correctly. If you see simply '1', then the Lanpaks were installed incorrectly, most likely to the wrong drive. Remember, the correct way to install Adagio is to have all the programs and lanpaks in the same place on a shared network drive, as opposed to installed locally on each persons local workstation.
You do not have to register the Lanpaks before they can be used - however after 60 days if they are not registered then they will expire.
Regards,
