Successful Installation...but not able to play?

[Bryry]

Ok so I installed the game on my laptop that has Vista. It worked great, I
got to play the game for a couple hours. That was a week or two ago and I
cant get my disk to work. Its not scratched, or dirty or smudged and it just
wont read the disk and keeps telling me to put in disk one..what can i do?

I've got a similar problem. Zoo tycoon 2 zookeepers edition installed and
working properly, but when i installed marine mania it keeps asking for the
disk although it's already inserted. (i tried both disk drives)....

I have a similar problem. I'm running "Zoo Tycoon 2: Ultimate Collection" on
a PC with 8GB of RAM running Vista Home Premium x64 SP1.

The games installs just fine (all three discs), but when I try to run it, I
keep getting the following message:
"Insert Zoo Tycoon 2: Ultimate Collection Disc 1 into your CD-ROM drive.
Select OK and restart the application.", although Disc 1 is in the CD-ROM
drive.

Has anybody found a solution to this problem?
