I purchased GK2, and installed it using Sierra Help's website.
Before using that, I had tried opening the game in DosBox on my own and it would not work. I read something about needing to use some patches but after downloading them I wasn't sure how to use them (not very tech savvy here!) So I was relieved when I found the above link. BUT when I started playing, I realized that the map only allowed me to travel between the Huber home and the city. There is no box to click to go to the zoo or police station. I'm not sure if this is due to the way I installed the game or not, and I'm unsure how to fix this issue.
