- The leftovers from buildings are masking the game
statistics that are displayed in the lower right corner of the window. There is
no workaround for this issue.
- Maintenance workers cannot be assigned any jobs nor do they
have any duties assigned. To resolve this issue, remove and then reinstall the
game on a clean booted computer.
- During some seasons, the game designers created special
effects that you may notice. For example, on October 31st you will see witches
flying on broom sticks, and the people in the zoo will all have orange
Specific Configuration Issues
If the Display Pointer Trails
check box is
selected in the Mouse Properties
dialog box before you play
Zoo Tycoon, the pointer will blink when you are playing Zoo Tycoon. To stop the
Zoo Tycoon pointer from blinking, click to clear the Display Pointer
check box in the Mouse Properties
Building Sections Disappear
When you have a line of buildings that run from the upper left to
the lower right of the screen and put a building perpendicularly near that line
and then move your view of the game screen so the newest building is near the
top of the screen, the building may not be displayed correctly. This is merely
a display issue. The building will function correctly. To view the building
normally, move your view of the game screen so that the building is toward the
center of the screen.
Saved Games Are Not Deleted When You Remove Zoo Tycoon
When you move Zoo Tycoon saved games to a folder other than the
Saved Games folder, those saved games will not be deleted when you remove Zoo
Tycoon. To avoid this, keep your saved games in the Saved Games folder in the
Zoo Tycoon folder before you remove Zoo Tycoon; otherwise, delete your saved
games manually from the folder you saved them in.
Empty Adopt Animals Panel
When you play a game that has gained animals through research and
conservation programs, quit that game, and then start a new game, the Adopt
Animals panel may be blank. To resolve this issue, scroll to the top of the
Adopt Animals panel, and the animals that are available in the game that you
have just started will appear correctly.
New Content Causes Crash
When Zoo Tycoon closes immediately after startup after you load
new content (animals or buildings), it is likely that you loaded a corrupted
file. To repair your installation of Zoo Tycoon, delete the corrupted file from
the Updates folder in the Zoo Tycoon program folder.
Restart the Game After You Add New Items
After you add new items to Zoo Tycoon by using the Zoo Tycoon
built-in feature for adding new items, a message appears that states that Zoo
Tycoon will restart automatically. If Zoo Tycoon does not restart
automatically, restart the game manually.
Reinstall Zoo Tycoon
When you must reinstall Zoo Tycoon or move it to a new computer
and you want to preserve your progress in the game, save the Zoo.ini file
(located in the Zoo Tycoon root folder) from the game that you plan to remove.
This file records the progress that you have made in Zoo Tycoon scenarios.
After you have re-installed Zoo Tycoon, replace the new Zoo.ini file with the
one that you saved. When you do not save the Zoo.ini file yourself, your
progress through the Zoo Tycoon scenarios will be lost.
Remove Updates from the Main Menu
You may add updates and additional content to the Zoo Tycoon game
from the main menu in Zoo Tycoon, but Zoo Tycoon will not delete them for you.
To remove additional Zoo Tycoon items, you must delete them from the Updates
folder in the Zoo Tycoon folder.
"Caretaker Having Trouble Getting to Exhibit name" Message
This message may appear when you have built a zoo that requires an
animal caretaker (zookeeper, scientist, or marine specialist) to walk a long
distance from exhibit to exhibit. The exhibit gates and paths may be clear, but
because the caretaker may have to walk around many buildings or scenery, it may
take a long time for the caretaker to reach an exhibit. This causes the message
to appear. To prevent the message from appearing, assign caretakers to specific
exhibits to keep them from walking too far from exhibits, pick up and move
caretakers closer to exhibits yourself, or build exhibits so they are close to
each other, thereby minimizing the time it takes for caretakers to walk through
Cancel Setup During Game Installation
When you cancel Setup during the installation of Zoo Tycoon
Expanded, some files that must be removed manually may be left behind. If you
cancel Setup and find that you are having problems playing, remove Zoo Tycoon
Expanded and reinstall the original Zoo Tycoon and any Zoo Tycoon expansion
Triceratops Escape after You Install Zoo Tycoon: Dinosaur Digs Expansion Pack
If you unlocked the Triceratops in the original Zoo Tycoon, you
will find that after you install Dinosaur Digs, the Triceratops will break out
of its fence. To resolve this issue, enclose the Triceratops by using
dinosaur-strength fence types.
Cannot Use Hotkeys After You Minimize the Zoo.exe File
When you minimize Zoo Tycoon by pressing ALT+TAB and then maximize
it by double-clicking the Zoo.exe file, you cannot use the hotkeys.
Not All Game Content Is Available After You Play Tutorials
When you complete the last Marine Mania tutorial and choose to
continue playing, you will not gain access to all the available content. Close
the tutorial and open a freeform or scenario game to gain access to all
Dinosaur Digs content.
Not All Items That You Must Have for Dinosaur Happiness Are Visible When You Use the Dino Only Filter
The content filters at the top of the item purchasing windows will
permit you to see original Zoo Tycoon content, new Dinosaur Digs content, or
both. However, not all items that you must have for dinosaur happiness (such as
certain rocks) are visible with the Dino Only filter. Use the All filter to
view all available content.
No Zoo Visitors Occupy the Bleachers That You Create Next to an Exhibit
When you create a set of bleachers next to an exhibit, you may
notice that Zoo visitors never occupy them. This may occur if you create the
a double-width path leading to the bleachers. If you delete one width of the
path, Zoo visitors will start to use the bleachers.
Restart Your Computer By Using a Clean Boot Procedure

programs. When you perform a clean boot, you prevent these programs from
