Include Your debug.err File
Browse to your /Documents/My Games/GalCiv3/ folder. Locate the debug.err file. This file includes information that we can use to determine why a crash or bug occurred. Please include this file when reporting bugs and/or crashes.
Find the Crash Dump File
Browse to C:\ProgramData\Stardock\Galactic Civilizations III\. This is a hidden folder so you may need to turn on the “Show Hidden Files and Folders” options in Windows (see http://support.amd.com/en-us/download for more information).
In this folder, locate the .zip file that matches the time and date when your crash appeared. These files are not created for every crash, but if you do have this file, it is very helpful for determining the cause of the crash, and ultimately fixing it.
Please include these .zip files when reporting your crashes.
