Below is a compiled list of the most common issues in Endless Space on PC. Note that some of these steps should be undertaken only if you are sure of what you are doing, and as such we always recommend you exercise caution when tackling the problems head-on yourself.
Manually download then install this update, if you have Windows 7 and you are encountering a pink screen then crash upon startup: https://www.microsoft.com/en-us/download/details.aspx?id=36805

If you are encountering issues launching Endless Space 2 with Win10, right click the game icon, go to Properties and in the Compatibility tab, tick the box "Run this program as admin". In some cases your Documents folder might be read-only, if that is the case be sure to change that setting too!
If the icon on your desktop is just a shortcut, find the Steam installation folder on your computer. For me it is: E:\Steam\steamapps\common\Endless Space 2 (default installation folder on my secondary partition), and select the Endless Space 2 executable.
Also worth a shot: running the game in compatibility mode for Windows 7. Same menu as above!
This will happen if you have special characters in the filepath for your game, such as the brackets in this example: [NORMAL] Program Files\[STEAM]\steamapps\
Try reinstalling the game in a folder with a filepath that does not include special characters.
There seems to be an issue mostly with HP laptops having both an Intel HD Graphics chipset and a discrete graphics card: the game starts, the video plays then the game crashes.
Open your graphic card's control panel and follow these instructions:
- NVidia control Panel
- Click on Manage 3D Settings.
- Click on Program settings
- Click on Add a program
- Select Endless Space 2
- Select "Apply"
- Close the Control Panel
- Restart your computer and launch the game.
- Catalyst Control Center
- Go to Graphics > Power Play - Set Plugged In and Battery to Maximum Performance. Click Apply.
- (on certain models) go to Graphics > 3D and push the slider to Performance. Click Apply.
- (on certain models) if you have a Switchable Graphics tab, go there, select EndlessSpace2.exe in the list of applications and set it to High Performance. Click Apply. (the defaut path for the application is C:\Program Files (x86)\Steam\SteamApps\common\Endless Space 2 )
Restart your computer and launch the game.
If you cannot save games it usually means there's an issue with writing in the My Documents folder.
Right click on your My Documents folder in the files explorer and go to Properties. Click on the Security tab, click on your username or session name, and look at the "System authorizations" list. Check that "Writing" is Authorized, otherwise click on "Advanced" and change it manually to Authorized.
