II. Game loading issues  

-Verifying your Game Cache within Steam / GoG Galaxy  

Steam: Follow this link to verify your Steam files for GalCiv3: VALIDATE 

GOG: Visit this image for an example of verifying your game within the Galaxy client: 

-Page File Size

Please make sure your virtual memory is set to default:


-Error 'The folllowing folders are in a state of partial install'

If you are running the game from a shortcut on your desktop, delete it and recreated from within Steam.

-Update Video Drivers
Please make sure your video drivers are up-to-date. Even if they are current, a full remove, and reinstall, would be prudent; especially if you have recently installed Windows 10

Use the link(s) below for updating:
Note: Please perform a "clean installation" if you have an Nvidia graphics card. The below screenshots will help with how to do that:  
For ATI \ AMD driver uninstalling: 
-Run Steam as Administrator

Exit Steam completely by right clicking it's icon on your taskbar. Next, right click the icon on your taskbar, then right click where it lists Steam, and select Run as Administrator.

-Re-Installing Redistributables

Download the redist file from the link below and install \ repair.     

-Re-Install DirectX

In the following location:

C:\Program Files (x86)\Steam\steamapps\common\Galactic Civilizations III\_CommonRedist\DirectX\Jun2010

Run: DXSetup.exe

Reboot and try to run the game again.

-Create a fresh Administrator Account

As a test, create a new Administrator (<--Important) Windows account and try to run the game again: 

If that works, for some people, we have seen that permissions for the 'My Games' directory have changed after a Windows 10 upgrade (fresh Windows 10 installs would not have the issue).  If you have recently upgraded to Windows 10, and GC3 will not load \ save \ save your settings changes, please download and run the following: 

If that fails, manually make certain that your 'My Games' directory, under your own Windows user account, has 'Full' permissions (write is the key).

-'Environment Variable Missing Path'

If you recived the above in-game error', press the Windows and 'R' Key at the same time. A "Run" dialog box should appear, paste the line below and click OK:

The "System Properties" menu should appear. Click the 'Environment Variable' button, and under 'System Variables' select the 'Path' entry and click 'Edit'. (Example:
What we believe may be missing for you is this segment (don't worry about comparing anything else of yours to the example posted above):
Win 7:
If the line above is missing, please add a 'New' line for Win10
For Win7, the full line, C:\WINDOWS\system32; ,to the very beginning of the data in the 'Variable Value' field. Example (not the whole long string, just C:\WINDOWS\system32;):
C:\WINDOWS\system32;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Program Files (x86)\Common Files\Microsoft Shared\Windows Live;c:\Program Files (x86)\Intel\iCLS Client\;c:\Program Files\Intel\iCLS Client\;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\
Click OK to save it, reboot your system, and try to run the game again.

 We are pleased that MODs are very popular. However, prior to placing a ticket, please mention if the issue you are having is not present if you do not use them (or have them installed).  While we may be able to provide nominal support for why the MOD may not be working, ultimately, if the game works without the MOD, the author of the MOD may be the best resource for resolving it. 

-'The Purge'

Please uninstall GC3 from Steam/Galaxy by following the instructions below.

STEAM: Right click GC3 in your Steam library and select "Uninstall...":

You will be prompted to delete the game(Dead Man's Draw is just an example):

GALAXY: Left click GC3 in your Galaxy library and select More, Manage, Uninstall:

You will be prompted to uninstall the game: 

***IMPORTANT*** Make sure you've completely exited Galaxy after uninstalling:

Open your Windows notifications window, right click the GoG icon and select Exit 

After GC3 has been uninstalled, please press the Windows key and "R" at the same time. In the window that appears, paste the path below and hit enter:

  %userprofile%\Documents\My Games 

In the "My Games" folder, if there is still a folder remaining called "GalCiv3" please rename it so a new one will be generated.

Once again, press the Windows key and "R" at the same time, and use the path below:


You should see a folder named "Galactic Civilizations III", please rename this as well.

Lastly, please navigate to the path below and delete the entire folder for GalCiv3:

STEAM: C:\Program Files (x86)\Steam\SteamApps\common\Galactic Civilizations III

GALAXY: C:\Program Files (x86)\GalaxyClient\Games\Galactic Civilizations III

Note: The path above assumes you've installed GC3 to the default Steam/Galaxy directory. You may need to adjust the path accordingly if it is installed to a non-standard location.

Restart your computer and reinstall GC3 using Steam/Galaxy. After it has completed the installation, please create a new save and let us know if you experience any further issues. 

-Check for available opt-in updates 
Start by turning off Steam Cloud saving here please:

To opt into the development snapshot, do the following:

Right-click the game in your Steam library
Select “Properties”
Select the “Betas” tab
Choose “Opt-in” from the drop-down menu
Close the Properties window

Example of selecting the opt-in:

Unless otherwise stated (ticket or from a forum post), you do not need to enter a 'Code'; closing will start the patch update.

After opting in to the patch, and if your save game still shows to have issues, please verify that they still exist with a new game. 


III. Graphical issues

Also see updating your Video card drivers above. 

-Low Prefs:

For clients with low-end video cards (especially Intel PC's with only integrated Video), try running the game with some lower base settings to see if that resolves some of your issues.

Please download the following Prefs.ini file and unzip it in the location following:


C:\Users\YOUR_USERNAME\Documents\My Games\GalCiv3

Gameplay Settings:

Galaxy Settings:

Try experimenting with these settings pointed out:


-Black Screen while using a Microsoft Surface:

If you're running the game at fullscreen, or a non-native resolution, please change the resolution to the Surface's native resolution or run in windowed mode.
