In the game launcher please set Display mode to Borderless.

IF that doesn't help, Has the game ever run successfully on this computer? Or never?

IF IT USED TO RUN:
Please do a full **clean** re-install:

- move any valued save games elsewhere, and user_empire_designs.txt from /Documents/Paradox Interactive/Stellaris/ if you have made any custom empires or races.
- "uninstall" in Steam-Stellaris
- manually delete both the Steam/SteamApps/common/Stellaris AND Documents/Paradox/Stellaris folders
- re-install game in Steam, run a Steam Verify when done.
- add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular you need to make sure there are no files or folders left under either the Steam Stellaris or Documents Stellaris locations, before installing again.

IF NEVER:
Install ALL these Microsoft modules:

Download Microsoft Visual C++ 2010 SP1 Redistributable Package (x86) from Official Microsoft Download Center

www.microsoft.com www.microsoft.com

Download Microsoft Visual C++ 2010 SP1 Redistributable Package (x64) from Official Microsoft Download Center

www.microsoft.com www.microsoft.com

Download Microsoft Visual C++ 2015 Redistributable Update 3 RC from Official Microsoft Download Center

www.microsoft.com www.microsoft.com
THEN go here:

The latest supported Visual C++ downloads

This article lists the download links for the latest versions of Visual C++. support.microsoft.com support.microsoft.com And run the x86 and x64 installers there.


Add stellaris.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.

Also if you have FRAPS or the MSI Gaming App or Rivatuner installed, disable it as it clashes with this game.

If that doesn't help:
DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Please attach your Documents/Paradox/Stellaris/settings.txt and pdx_settings.txt .
From your Documents/Paradox/Stellaris/logs/ folder, attach system.log , error.log .

Your Windows 7 installation is a bit out of date. Did you run all those MS installers I listed? Any error or problem doing so?

Exit the Steam app entirely and run stellaris.exe directly from Windows Explorer, do you see any error when it fails now?

Please attach your Documents/Paradox/Stellaris/settings.txt and pdx_settings.txt .
From your Documents/Paradox/Stellaris/logs/ folder, attach system.log , error.log .
