@ALBUS concerning step 10:

Double click MARINE.iso (as if you would open the file). Depending on your Finder settings, "MARINE" will appear in the Finder sidebar under "Locations". Once this is done, the "CD error" will go away. Hope this helps.

Albus 2022-08-14 0 point Mac version

SCHNEIPI thank you that has helped get past step 7 and it now gives the cd error, could I ask what step 10 means and what it means to "mount" marine.iso

Schneipi 2022-08-14 1 point Mac version

@ZT_FIEND concerning step 7:

Just open the Terminal app and type:
xattr -cr /Applications/Zoo\ Tycoon\ -\ Complete\ Collection/.Zoo\

This should work in case "/Applications/Zoo Tycoon - Complete Collection/" is the path where ".Zoo" is located on your Mac. After typing this, run the command by pressing Enter. That's all, you can close the Terminal window again.

Also, sorry for not numbering the steps correctly and skipping step 14.

ZT_fiend 2022-08-14 0 point Mac version

SCHNEIPI thank you so much for your detailed guide. I could only make it to step 7 or so before halting (I have no idea what I'm doing in Terminal). Any chance there is a video explanation of this somewhere that any one knows of? I am fiending to play Zoo Tycoon tonight lol :)

Schneipi 2022-08-07 12 points Mac version

Concerning the Mac version, here is what I did to run it successfully and get rid of the "CD" and "is damaged" errors:

1. Download and move the Mac version into your Applications folder.
2. Run the main "Zoo" (Right Click Open).
3. "Mounting Fake Image ..." window appears, just wait until it closes again.
4. Next, press Command + Shift + . (period) to show hidden Finder files.
5. Locate ".Zoo", which should be in the same folder as "Zoo".
6. When trying to run it, it will say that it is damaged.
7. To work around this, open "" and run "xattr -cr [Path to .Zoo]".
8. Now try running it again, this time it will complain about the CD.
9. To work around this, download the regular Windows .iso version.
10. Next, mount MARINE.iso.
11. This time, ".Zoo" should run regularly.
12. Use "Change Resolution.command" to adjust the resolution (using half of the actual Mac width and height worked best for me).
13. Delete all files within the folder, except ".Zoo".
15. Rename ".Zoo" to "Zoo", so that it unhides.
16. Press Command + Shift + . (period) to disable showing hidden Finder files.
17. Move MARINE.iso to the folder, so it is bundled with the main app.
18. Don't forget to mount MARINE.iso before you start playing.

Enjoy :)

The game worked great for me but Daemon put malware on my computer. DO NOT DOWNLOAD DAEMON. Hopefully someone can suggest a better alternative :/

ROX 2022-08-06 0 point Mac version

I have the same problem of MISSMOZART!
I cannot launch the game as soon after doing what ALBERT suggested I get the messagge ".Zoo Tycoon” is damaged and can’t be opened. You should move it to the Trash.
Someone knows how to fix this issue?!
Thank you!!

anon 2022-07-26 0 point Windows version

Here's some help for anyone trying to install the bonus animals. And anyone who gets the CD error.

First, unzip the downloaded files and leave the contents as-is. When you open up the game click "Get New Zoo Tycoon Items", and choose to download locally. Navigate to where you placed the downloaded files from earlier and load in all the .dll and .ztd files. There also might be more you can get from the actual Zoo Tycoon website when using the Wayback Machine at the url ""

For those who get the CD error, go where you downloaded the game; it should be in a folder labeled "Microsoft Games" where you downloaded it. Copy the zoo.exe in the main Zoo Tycoon directory and place it someplace else. Then replace the one back in the main directory with the patched one you get from here and it should work. Sometimes it says you still need the CD but I just restart the game and it works.

Neuro109 2022-07-15 0 point Windows version

I did what KC did and it works great!

1. rename zoo.exe to zoodemo.exe (the "application" file named zoo to zoodemo)
2. An ini ("configuration settings") file named zoo generation. I renamed that to zoodemo.
3. When prompted to insert the disc I mounted both Zoo Tycoon and Expansion Pack iso's.
4. Run the zoodemo.exe and it works great!

I am using Windows built in iso mount feature to install and run.

I followed the steps that ALBERT gave to fix the issues that HAMAYA and ME explained. But when I got the hidden .Zoo Tycoon file and wanted to open it it tells me this:
“.Zoo Tycoon” is damaged and can’t be opened. You should move it to the Trash.
Any idea what I should do?

Thanks for any help given!

Albert 2022-06-14 0 point Mac version

Because the Bundle is not signed the sh** Gatekeeper is complaining about it. Allow the App to Launch in System/Security Section.

@ ME:
Is a Volume "MARINE" on your Desktop? If it is start Zoo Tycoon App manual. The Package is hidden so press these Keys to see it:
Command + Shift + .

I think it´s the same as HAMAYA. Gatekeeper is blocking it. Allow it and it should run.

How do I get it to open? all I get is a message saying "Destination file cannot be created" Im not sure what this dameon thing is or how to get this to work. Thank you for any help!

Downloaded this, it worked for 2 weeks absolutely fine, completed nearly all of the scenarios then my save file somehow got automatically deleted and the game would not load and kept coming up with a run error (no CD inserted) tried the NO CD patch just said the file did not exist. Had to uninstall, can't find the save file anywhere and then reinstall it! :(

Attention. If you use a No-CD crack the Zookeepers won't tidy up the park nor repairing anything! You must Play the Game with CD2 inserted and the original exe.

Playing it on a Wine Wrapper on MacOS with the latest Wineengine (21CX) flawless.

aron 2022-01-05 1 point

if you wanna play without the cd here is a guide
1.get the nocd file
2.go to C:\Program Files\Microsoft Games\Zoo Tycoon
3.Replace the zoo.exe with the nocd one
and if its not in Program Files its probably in the 32 bit folder

Screamingrock 2021-11-01 1 point

If there's anyone who couldn't run the game, change 'zoo.exe' and 'zoo.ini''s name to 'zoodemo.exe' and 'zoodemo.ini'. You'll find the game working perfectly. Enjoy!

Avva 2021-10-17 0 point

DO NOT FOLLOW SC GIRL'S GUIDE, more specifically, don't install Daemon Tools they will put adware all over your PC. I suggest deleting immediately and using another software that's more trustworthy.

How do you download mods?

SG Girl 2021-07-31 -4 points

Copied this comment from a post (credit to THE FRENCH GIRL from this link

If you have difficulties in loading , please try this method.

If you download Zoo tycoon 1 on internet and you don't have a disk, here is a solution:
Step 1 : Make sure to download the game as a compress folder with a CUE file
Step 2 : Download Demon tool - the software allows you to turn CUE files into disc and create game support
Step 3 : Open Demon Tools. At the Bottom on left, click on "Quick Mount"
-this step is obligate every time you want to launch the game -
Step 4 : The creation of the CD disc is made, you must see the icone when you open 'This PC' , it will be in "Devices and drives" next to "Windows C"
Step 5 : Then run the game installer until the last step
FINAL : Start the game and the problem should be fixed!

==Don't forget to do the step 3 every time you turn off/on your computer to play !

Kenobi 2021-07-20 3 points

How long should it take to download? A couple of minutes at most right? At least that's what I would think since it is only 1 GB. Why does it say it'll take an hour? Is there something else I need to be doing or is something wrong with the file?

I'm not super sure about this version (i bought the base game before) but for those wondering how to get the aspect ratios to work properly, there should be a zoo.ini file in your zoo tycoon folder. Open it and scroll down until you see screenwidth and screenheight, then just replace the numbers next to it with your screen aspects and you're good to go. Hope this helps :)

Theepieguy 2020-08-30 1 point

For those having problems with "Insert CD" errors and the like. Windows likes to do something silly whenever it updates- it un-mounts all CD's. So if you still have the MARINA.iso (Which there shouldn't be a reason you do not.) That's the ISO you need to mount once again with a right click. I just created a shortcut to it on my desktop next to the complete collection icon and re-mount the file with a right-click on the shortcut. That should fix anyone's Insert CD problems.

APenguin 2020-08-26 2 points

So I worked out why KC's fix works, and can recommend a shorter route for anyone. In the ini file, just change fullscreen = 1 to fullscreen = 0 and it should boot fine. Seems to be an issue where a lot of older games crash on startup on windows 10 if they are fullscreen.

LaBg 2020-08-20 0 point

Dear ZSO, hire a zookeeper. Maintenance workers are there to clean up garbage and fix fences, not feed the animals. I'd recommend playing the tutorial :)

Sophie 2020-08-13 0 point

Downloaded OK, but when I try to open it says 'please insert CD ROM'. I tried the 'NOCD' file thinking maybe that is meant for that, but it doesn't open anything. Is there anything I can do?

Anon 2020-07-16 1 point

Works fine, I haven't got any problems (win 10)
You have to mount the zoo iso file and then the marina file which contain both expansions. If you have the no CD error just use the NOCD exe.

Aristocat 2020-07-14 1 point

My game starts fine. However, crashes after 5 min of gameplay.
If anyone knows a fix please let me know.

kc 2020-06-14 9 points

For anyone having trouble running the game, here is what I did to make it work on my windows 10 laptop:
1. I started by doing what everyone else in the comments said to do: mount the game via daemon tools and install it. The problem was that clicking on the game did not result in anything.
2. I watched a youtube video which told me to run the game in Windows XP compatibility mode. Same result.
3. I saw a suggestion somewhere to rename the zoo.exe file to zoodemo.exe. This caused the loading screen to pop up and then disappear.
4. In a last ditch effort, I tried copy-and-pasting the contents of zoo.ini into zoodemo.ini (which was automatically created when I renamed the exe file). THIS WORKED. I don't know why, but it did. Not that these files are found inside the Zoo Tycoon folder of your program files.

I don't know why this worked, but I decided to post it in case it helps anyone else.

I just downloaded this and ran it using Wine HQ on my Mac. It worked perfectly!

- download the file
- open it, type wine then open the downloaded folder and drag the "setup.exe" file into wine. this will set up the game. When you click play the game it will give you an error. Just open wine again, type wine, then drag in the setup.exe file one more time. Click play and you should be good to go!

Becxter 2020-03-24 8 points

This is what worked for me:

To run the base game in Daemon, use "quick mount" and select the ZOO_TYCN file. You will do this to launch the game each time.

To utilize the expansion packs, do the process listed above, but choose the file, "MARINA". Install, and then open a saved zoo file from the base game (unsure if this part is even necessary, but I was already playing the base game). A pop-up should say that new animals and such are available.

Brooke 2020-03-24 -3 points

For the people who are getting the error message about "please insert CD", go to your File Explorer and open up the CD Drive. In there you should find the game! There will be several folders, to start the game select the folder labeled "Setup"
