Well Howdy, banmenowBK! Nice to meet a new member - and on your very first post, too!
I'm making an assumption here (which is always dangerous) :lol that you downloaded a zoo from the ZA Downloads section and you want to know how to install it? Either that, or you've downloaded a Scenario hack from the ZA Scenarios/Hacks section? If, and ONLY if that is the case, that zoo is to be unzipped to:
C:\Documents and Settings\
YOUR NAME GOES HERE\Application Data\Microsoft Games\Zoo Tycoon 2\Default Profile\Saved
and it's
YOUR actual name that goes there, whether it's John/Alice/Administrator/Owner/Mine/Home
Now, if that does not work, or if that is NOT what you're asking, please post again with a little more information. Now that we've done with that, go on over to
Introductions and meet the rest of the gang! You'll find cookies on the hall table... :happy
