If Oxygen Not Included is getting stuck on the Klei Logo or crashing at the Klei logo when you are trying to launch the game, please follow these troubleshooting steps to resolve it:
WINDOWS PC
- Ensure that your Windows User account has provided Steam the proper administrative permissions to launch the game as well as to be able to read/write your hard drive.
- Unfortunately malware, firewall and virus protection programs can be a bit unpredictable at times. Try disabling anything you have running (or forcing your security or antivirus software to allow Steam or the game.exe to be able to read/write your hard drive) then try running the game again. Pop-up blockers, ad-blockers, and other types of software running in the background can also sometimes cause problems. Turn off anything you have running in the background then try running the game again.
- Verify that Steam has properly downloaded the game by going to Oxygen Not Included in your Steam library. Right click on Oxygen Not Included in the game list, and select Properties > Installed Files > Verify Integrity of Game Files.
- Try resetting the game to its default setting values by deleting a file called "kplayerprefs" in the OxygenNotIncluded folder in your Documents folder. Go to C:\Users\{Your Windows User account}\Documents\Klei\OxygenNotIncluded\ and delete the "kplayerprefs.yaml" file
- If you have MODS installed, please delete the mods directory at C:\Users\{Your Windows User account}\Documents\Klei\OxygenNotIncluded\mods, then unsubscribe all of your mods from the Steam Workshop to see if one or a couple of the mods are causing the issue. From there, enable them one at a time.
MAC OS
If Oxygen Not Included is getting stuck on the Klei Logo or crashing at the Klei logo when you are trying to launch the game on Mac OS, please follow these troubleshooting steps:
- Reset the game to its default setting values by deleting a file called "kplayerprefs.yaml" in the game settings folder. Go to ~Library/Application Support/unity.Klei.Oxygen Not Included and delete the "kplayerprefs.yaml" file.
- Verify that Steam has properly downloaded the game by going to Oxygen Not Included in your Steam library. Right click on Oxygen Not Included in the game list, and select Properties > Installed Files > Verify Integrity of Game Files.
- If you have MODS installed, please delete the mods directory at ~Library/Application Support/unity.Klei.Oxygen Not Included/mods, then unsubscribe all of your mods from the Steam Workshop to see if one or a couple of the mods are causing the issue. From there, enable them one at a time.
