The app won't update or won't open

Updated November 15, 2026 · 3 min read

Devchaos updates itself: it downloads a new version in the background and installs it when you press Update or quit the app completely. If it seems not to open, it is usually already running in the background.

How updates arrive

Shortly after it starts, and every four hours while it stays open, the app looks for a new version; you need to be signed in for that. When it finds one it downloads it, and Update appears in the title bar. Press it: Devchaos closes, the new version installs and the app opens again.

To look yourself, press Settings › About › Check for updates, or right-click the Devchaos icon next to the clock and choose Check for updates. What changed is in What's new.

If the update didn't install

If setup says “The update couldn't be installed; Devchaos opens with its earlier version.”, right-click the icon next to the clock and choose Quit Devchaos. Then download the latest setup from the download page and run it. Setup says Devchaos is already installed; choose Update or Repair. Your settings, sign-in and shortcuts stay as they are.

If it won't open or the screen is empty

  • Closing the window leaves Devchaos running in the background. Look among the icons next to the clock and click the Devchaos icon. Opening the shortcut again also brings the open window to the front.
  • If the window still doesn't come, right-click the icon, choose Quit Devchaos, then start the app again.
  • If it says Something went wrong, press Reload.
  • If the screen stays empty, try Restart from the icon's menu; if that doesn't help, run setup again and choose Repair.

Something went wrong?

Update never shows up.

Most likely you're on the newest version; Settings › About says “You're on the latest version”. The app only looks for updates while you're signed in.

It says “Couldn't check for updates”.

devchaos.com couldn't be reached at that moment. The app tries again later by itself; check your internet connection.

Setup says “Some Devchaos files are in use”.

Devchaos is still running. Choose Quit Devchaos from its icon, then press Try again.
