If you're encountering issues when launching or playing Endless Space, make sure everything installed smoothly.
Exit Steam entirely.
Browse to your Endless Space installation folder (Usually C:\Program files\Steam\Steamapps\common\endless space\)
Run the following installers:
Reboot your computer and test any issues again. If the issue persists, contact Endless Space support.
If the above does not resolve the issue and you are running Windows 7 or Windows Vista, please complete the instructions in our Windows 7 and Vista Troubleshooting FAQ.
If you are running in Windows XP, take the following steps:
Go to C:\Users\USERNAME\Documents\Endless Space\Users\USERNAME there is a file called Registry.xml. In a text editor open it and change the values manually. Note that you may have to change the refresh rate to 59, and the file to read-only.
To find your current refresh rate, run DxDiag. In Windows 7 this can be done by typing 'DxDiag' in the Start Menu. Go to the 'Display' tab, and look for the 'Current Display Mode' field. This is the resolution and refresh rate of your desktop, and probably what you should use. Round down for the refresh rate. 59.95 should round down to 59.
By default your Registry.xml should have a section that looks similar to the code below. If it does not contain all 4 of the video fields, you're editing the wrong file.
Changing it to work in 1920x1200, the fields now look like this.
Locate the Registry.xml file in the following directory: /Users/USERNAME/Library/Application Support/Steam/SteamApps/common/EndlessSpace. Open the file in a text editor and the follownig section of code is where you can edit the resolution. The below example shows resolution at 1920x1080 at 60 Hz.
Inside the game folder located in Steam (...\Steam\Steamapps\Common\Endless space\), try deleting all files with the .vdf extension.
Visual C++ Redistributable is not properly installed on your system. To insure that it is, you need to first uninstall your existing 2010 VC++ Redist from the Windows Control Panel. Once this is done, you need to go to the following location: ...\steam\steamapps\common\endless space\components\
Then, run the “vcredist_x86.exe” you find to reinstall that component. It is important that you restart your computer before launching the game again. If the issue persists, contact Endless Space support.
Make sure your firewall adds Endless Space as an exception. If you are using Comodo, make sure you have enabled "Game Mode".
If the issue persists, you will need to troubleshoot the issue with Endless Space Support.
