Update Flow Launcher Without Losing Your Setup

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

At a glance

Before updating Flow Launcher, back up the active UserData folder and record how you installed the app. Update through that same installation method, then verify the app and plugins separately. Version compatibility matters: the 2.x branch changed Windows support and the default-plugin framework.

Steps to follow

  1. Open About and record the current Flow version. Identify whether this copy came from the installer, portable ZIP, WinGet, Scoop, or Chocolatey.
  2. Locate UserData from Flow, close the application, and make a dated backup. Include custom themes and plugin configuration rather than only the executable.
  3. Read the target release notes. Apply the update with the current install method and avoid running two different app folders during migration.
  4. Reopen Flow and test app search, file search, and an important plugin individually. Check for plugin updates only after the base app works.

Check the result

The expected version appears in About and your hotkey, theme, and saved paths remain usable. A plugin-specific error should be reproducible without affecting basic app search.

Limits and common pitfalls

Installing newer plugin files into an older Flow branch can introduce incompatibilities. Keep an application/profile backup pair, not just one old EXE.

Make the check repeatable

A useful update record includes the source version, target version, Windows build, backup path, and the first failing feature, if any. Do not reset all settings before isolating a single failing plugin: doing so removes evidence and makes it harder to reproduce the original issue.

Questions and answers

Will all old themes work after a major update?

Not always. Release 2.1.0 changed the UI framework; themes using the old ModernWpf namespace may need migration.
