Zoo Tycoon 2 install on Laptop help!?

Well, I have successfully installed Zoo Tycoon 2 on my home computer, but my computer is now infected with around 30 critical viruses, so it doesn't, sadly, allow me to play Zoo Tycoon anymore. So anyways, I am trying to install it on my dad's laptop. It was installed before, but wasn't working, so I, not thinking, uninstalled it in hopes that if I installed it again, it would work. It let me uninstall it, but when I insert disk 1 into the computer, the button to install it comes up. So I click on it, and it then asks me which features I would like to remove, "Remove save game" or "Remove downloaded content." So I tried clicking both, and then every time I do that, it uninstalls the game again, even though I pressed install in the first place. What should I do so the laptop lets me install it? I also have Zoo Tycoon 2 Marine Mania that I need to install... Please help! Thank you and have a nice day (:
