Project Zomboid is an open-ended zombie-infested sandbox. It asks one simple question – how will you die? Whether surviving in Knox County free-roam or controlling Indie Stone mascot Baldspot in his quest to save his injured wife Kate – death is always a certainty. Quite how long you manage to put it off is another matter…

Greetings troubled survivors! If you’re having issues getting Project Zomboid up and running on your machine then run on in here, and barricade the door behind you.


TODO

  • Make sure that you know what OS you have installed, as well as if it is 32Bit or 64 Bit.
  • You will also want to make sure that your OS is up to date.
  • Make sure you have the latest version of Java installed. Download the one corresponding to your OS fromJava.com
  • Make sure you have the right Java version installed and are running the corresponding game version. The 64x version of the game will not work when you have a x64 system but only 32Bit Java installed.
  • Some graphical glitches might be related to old or outdated video drivers. Make sure they are up to date. If you think they are, download them again anyways. This is to double check.
  • Playing on a laptop, make sure you’re not running the device in Energy Saving mode while playing the game.

COMMON SOLUTIONS AND FIXES

Reinstall/Update Java
Sometimes your Java installation may end up being corrupted and/or out of date. To fix this, uninstall Java. Once it’s removed from your system. try reinstalling it.
Java can be downloaded/updated via the Java Download page :
Java.com

Update your video drivers
Note: Some manufacturers (Alienware, sometimes Toshiba, etc) are putting out their own drivers so you should check out your manufacturer’s website, first.

Do not trust Windows with updating your drivers. Also, do not blindly trust any auto-updater (no matter if it’s from the manufacturer or a third party application).

ATI/AMD
For downloading ATI/AMD Drivers, head over to Support.amd.c...ages
Your Catalyst Control Center is also able to tell you if your driver is out of date and update it.

NVIDIA
The drivers for your nVidia GPU can be downloaded here: Nvidia.co...aspx?lang=en-us
To automatically detect your video driver updates for your nVidia GPU, check Nvidia.co...nload

INTEL
To download the drivers for Intel graphics chipsets, head over to Downloadcenter.intel.com
You can also check the following link to let them look for updates automatically: Intel.com...support

Try running the game in safemode:
You can use safemode by simply right-clicking on the game in the Desura or Steam client and then clicking “Compatibility Mode 32x” or “Compatibility Mode 64x” depending on your OS and Java version.

_________________________________________________________________________


Q. I just downloaded the game on Steam and the game simply crashed on launch!
A. Please reinstall the game. Right click the game in your Steam library and select “Delete Local Content…”. Once that’s done, download the game again.
Also try to run the game from the .bat-file in your SteamApps\common\ProjectZomboid or Desura\common\ProjectZomboid folder.

Q. What is “Compatibility Mode”?
A. Compatibility mode uses compressed textures to reduce memory usage. This is recommended on integrated graphics cards/chipsets where normal mode causes low FPS.

Q. My PC specs are good enought to have a stable 30 or 60 FPS but I am getting really low FPS!
A. We have plans to improve the framerate dramatically in the upcoming weeks, so performance might indeed vary from what you would expect. Please consider playing the game in a lower resolution (1280*720, lower if necessary). Please also try locking the game to 30 (or 45/60) FPS in the options menu.
If you are using Gamebooster or an equivalent application, please turn it off, as testing has shown that it drastically reduced performance in many cases.
For further tips and performance reports, please check out the following thread on our forums:
Theindiestone...ing-fps-issues

Q. "The system cannot find the path specified" is displayed when I try to run the game.
A. Make sure you have the right Java version installed for your system.
If you’re running a 32 Bit OS you need to download the 32 Bit version of Java.
On a 64 Bit OS, you can have both 32 and 64 Bit Java installed, however you need to make sure to run the correct version.

If you’re using the Desura client, right click the game and select either “Play 32x” or “Play 64x”, depending what kind of OS you’re using and which Java version you installed.
On Steam, right click the game and select “64 Bit” for the 64x version of the game.

Otherwise, you need to run the corresponding exe-file which is either “ProjectZomboid32” or “ProjectZomboid64”

Q. I don’t have Java installed! / Where can I get Java?
A. If you’re playing PZ through the Desura client, Desura downloads and installs Java for you.
To do this
1) right-click “Project Zomboid Alpha” in Desura
2) click “Verify”
3) check “Re-Install tools”
4) hit the “Verify” button

You can also download Java via the following site:
Java.com

Q. I see a dark flash, maybe some text, and nothing happens!
A. Most of the time, this is the “The system cannot find the path specified” error, which means your Java installation cannot be located.

Q. The game does not start and I get the following error in the cmd window: “org.lwjgl.LWJGLException: Failed to set display mode (-2)”!
A. Resolve this by deleting the content of the following directory:
C:\Users\*yourUsername*\Zomboid[

Q. I made my resolution too high and now I can't access the options to change it (because the menu button is off screen)?
A. Delete your "options.bin" file in \username\Project Zomboid\ folder.

Q. I’m getting an error when launching it in Desura: “Failed to launch item Project Zomboid, File is not valid exe”
A. Delete the “Project Zomboid” directory from your Desura or Steam Folder, restart Desura or Steam and then re-install Project Zomboid.

Alternatively, this may be due to using an older version of Desura.
In that case, please uninstall Desura completely. Make sure there are no files left of it by going to the install directoy yourself (making sure it is NOT there anymore). The default install directory is C:\Program Files (x86)\Desura or C:\Program Files\Desura for systems using a 32 Bit OS.
When you made sure Desura is uninstalled, download the latest version and install it: Indiedb.com

Q. Buttons don't seem to work and text fields don't seem to have borders!
A. If you've recently resized the window, please restart the game.

Q. When changing from a smaller resolution to a larger resolution then starting the game, I seem to be zoomed in on my character. How do I fix it?
A. It's necessary to restart the game on any changes to graphics settings.

Q. I can't seem to change any of the zombie options in Sandbox!
A. Be sure to uncheck "Proper Zombies" to enable customized zombies

Q. Where are the other survivors? I sometimes hear sounds that indicate that they must be somewhere!
A. NPCs are currently not implemented.
The sounds are currently there as a glimpse at the upcoming meta-game events.

Q. I cannot load my save game!
A. Please see this thread on our forums: Theindiestone...oad-what-to-do

Q. Where are my save files located?
A. Save files are located in &#xus;ername%\zomboid\survival and &#xus;ername&#xzo;mboid\sandbox (e.g. C:\Users\YourUsername\zomboid\)

On Mac and Linux the saves are in Users//Zomboid/ or //Project Zomboid/

Q. I’m having a hard time to orientate. Sometimes I end up in a large empty area. Is there a map available?
A. A map can be found at the PZWiki: Pzwiki.net
User blindcoder is working on a zoomable and panable map out of screenshots which can be found here: Pzmap.crash-override.net
We plan to implement ingame-maps, at some point in time.

Roads without markings and lane stripes are usually a good indicator that you’re currently in an unfinished area.

We could have put markers in surrounding the filled areas but this would slow down map development down with repeatedly having to move markers back and on top of that, doing that would imply that there is nothing beyond the borders which isn't entirely the case. There is stuff out there, it's just sparsely distributed.

Q. I am having X problem using a Controller and/or Splitscreen Multiplayer!
A. Controller and Splitscreen Multiplayer support is currently just experimental. We’re aware of those features being fairly raw and undeveloped but this will change soon.

Q. "Cannot load server.dll"
A. You are likely trying to use the 64-bit version on a 32-bit system. Run the 32Bit version of the game. Via Desura that would be “Play 32x” or “Compatibility Mode 32x”. On Steam, you would just right click it and select either “Play Game…” or “Compatibility Mode”

Q. There is some error in my command prompt saying something about “Access is denied” and “Exception in thread “Thread-5”!
A. This is happening to very few people. Name your savegame with only one letter and it should work.
If it doesn’t try deleting the content of the following directory:
C:\Users\*YourUsername*\Zomboid
