Mine is in a case that is the same size as a regular DVD case, but is fatter and also has 3 CDs. It says Frogwares and The Adventure Company on it.
Are ya kidding me! I've been trying to get this game installed on my Windows 8 for some time now and had finally given up. During the initial Install Shield, I get a long numbered error code. Which I have looked up and didn't find much help for. Oh, well. I'm just glad you got it to install for you.
I'm not sure about this, but I don't think you see the Tages drivers if they are on your system. At least that's what I remember from my Windows 7 drive. Of course, the operative word here is "remember!"
Heading out to the gardens!
