Doomsday wont open

Im on windows 10, Ive recently installed it and it played no issues, i closed out to play something else and now whenever i press on the shortcut or the exe file in folder it would only show the small loading square, then it would just vanish not opening the application. Ive tried waiting, reinstalling it, repairing it and nothing has worked. it doesnt even show up as a running task in the task manager.


  • Sounds like there is a fatal error during launch that doesn't get reported in the UI.

    One thing you could try is clearing out some of the runtime files, in case these have been corrupted due to buggy file handling. Go to Doomsday's runtime directory "C:\Users\YourName\AppData\Local\Doomsday Engine\runtime", and delete the following:
    • "cache" directory
    • "persist.pack" file
    The "cache" exists only to make launch and other operations faster, and will be recreated on the next run. "persist.pack" contains some settings like window position that will get reset to defaults.

    Your savegames and game configs will be unaffected.
