Flow Launcher Not Opening: Process, Hotkey, or Window

Troubleshooting · Published October 30, 2026 · Publisher: flowlauncher.app

At a glance

When Flow Launcher appears not to open, determine whether its process is absent, running without a visible window, or failing on launch. Test normal application launch before focusing on the hotkey. Keep your settings intact until you have a reason to suspect the profile.

Steps to follow

  1. Open Flow from its Windows shortcut and inspect Task Manager or the tray for a running instance.
  2. If it is running, test the configured hotkey and check whether the search or Settings window is off-screen.
  3. If it exits or reports an error, record the exact message, Flow version, install method, and Windows build.
  4. After backing up UserData, isolate recent plugins or theme changes. A fresh-profile comparison is a later reversible test, not the first action.

Check the result

You can classify the failure as startup, activation, window placement, or a reproducible crash. That classification determines the next repair step.

Limits and common pitfalls

Do not repeatedly launch many copies, delete the whole profile, or disable protection without identifying the error. An unexpected downloaded executable should not be run simply to test it.

Make the check repeatable

A useful report states what happens when the executable is opened directly, not only when Alt+Space is pressed. Include whether the process remains running and whether another launcher responds. This gives maintainers a reproducible starting point without exposing personal configuration.

Questions and answers

Why is the tray icon visible but no search box appears?

The app may be hidden, the hotkey may conflict, or the window may be positioned off-screen. Check those before reinstalling.
