Well, I hope I didn't answer this in another topic, but, some of us have had that same problem and the solution (which just applies to ZT2 and ZT2 ES) seems to be:
1) [/b] after unzipping (you will need WinZip) the files to C:\Program Files\Microsoft Games\Zoo Tycoon 2
2) [/b] inside that folder, you'll see another folder, created by the MAKER (e.g. exitree, penguinman, martin1990)
3) [/b] inside THAT folder will be yet ANOTHER folder (e.g. arctic fox), plus a .dl file also called arctic fox
4) [/b] cut the zoo tycoon 2 file (inside that 2nd folder) and paste it next to the arctic fox .dl file
5) [/b] Now you have two files side by side, both named arctic fox
6) [/b] then, take both THOSE files (artic fox.dl and arctic fox.zoo tycoon 2) and CUT and PASTE them into
7) [/b] C:\Program Files\Microsoft Games\Zoo Tycoon 2
8) [/b] This virtually always fixes the 'non appearing' problem.
Some computers are configured differently, and some won't 'recognize' those individual folders. Mine, for instance, won't. I always have to do the above to get my downloads to work. Hope that helps! :happy
