Game does not start on Windows

I had the DLC running on 2 machines.

The first machine crashed and now only loops the DLC activation. No matter how many times I enable it, it never takes hold. tried to enable 5 times and verified files each time. the DLC will not activate.

The second machine was a hot mess. Crash then reinstall failed files. The DLC activation disappeared and only the base game stable build is running with no option to enable the DLC.

Integrity check solved the problem for me.

Hi, we're still trying to figure out a reliable solution for clearing the startup crash. It seems that some old files from the DLC are getting stuck in the install folder. Some things to try:

• Right-click ONI -> Properties -> Local Files -> Browse local files .... go into the OxygenNotIncluded_Data folder and delete StreamingAssets, then Properties -> Local Files -> Verify Integrity of Game Files
• Uninstall and reinstall the game through steam
• Browse to the local files as above, uninstall the game, after uninstall finishes delete any files that are left over in the SteamApps/common/OxygenNotIncluded folder, and then reinstall.

Please be careful when deleting files on your hard drive, and let us know if any of these solutions fixes the problem for you so we can share the information!
