I received this as a gift. I cannot install it. My Mac is just 4 years old this month, but my operating system (OSX 10.5.8)is too old to use the Adobe Air 3.1 that is required to open the Advent Calendar. Macs with at least OSX 10.6 are needed to install the calendar. I think this is deceptive in that the demo works fine on all computers. If you tried the demo, wouldn't you think the Calendar would work? I have contacted them several times, but haven't gotten a reply.
I think there should be a much bigger disclaimer about needing a newer computer to access the program.
