Weesper Neon Flow 1.5.1 on Windows: How to Reinstall the Stable 1.5.0

What Happened

On April 13, 2026, we released Weesper Neon Flow 1.5.1. Shortly after publication, we identified a crash affecting some Windows installations of 1.5.1. To protect users, we immediately withdrew 1.5.1 from our public release channel and rolled back to the stable 1.5.0.

If you downloaded and installed 1.5.1 on Windows and are experiencing crashes, this guide will get you back up and running in under 2 minutes.

Your data is safe. Your settings, license activation, and transcription history are stored separately from the program files and will be preserved throughout this process.

Who Is Affected

• ✅ Affected: Windows users who downloaded and installed Weesper Neon Flow 1.5.1 manually from GitHub Releases between April 13 and the rollback.
• ❌ Not affected: Users currently running 1.5.0 or earlier. Your app will stay on its current version and receive the fixed 1.5.2 automatically when it ships.
• ❌ Not affected: macOS users. This issue is Windows-specific.

If you are unsure which version you have installed, open Weesper Neon Flow and check the About dialog from the app menu.

Recovery Steps

Step 1: Uninstall Weesper Neon Flow 1.5.1

Windows Installer does not allow installing an older version of an application on top of a newer one. We therefore need to remove 1.5.1 first.

1. Press Win + I to open Windows Settings
2. Go to Apps → Installed apps
3. In the search box, type Weesper Neon Flow
4. Click the ⋯ menu next to the app, then click Uninstall
5. Confirm the uninstall when prompted

Important: The uninstall only removes program files. Your personal data — settings, hotkey, language preferences, license activation, and transcription history — is stored in %APPDATA%\WeesperNeonFlow\ and is not touched by the uninstall.

Step 2: Download the Stable 1.5.0 Installer

1. Visit https://weesperneonflow.ai/en/download
2. Click Download for Windows
3. Save the file Weesper-Neon-Flow-Windows-x64.msi to your Downloads folder

Our website and auto-updater both serve the stable 1.5.0 — you do not need to look anywhere else.

Step 3: Run the Installer

1. Double-click the downloaded Weesper-Neon-Flow-Windows-x64.msi file
2. If Windows SmartScreen displays a warning, click More info → Run anyway (the installer is digitally signed with a verified code signing certificate — see our SmartScreen guide for details)
3. Follow the setup wizard to complete the installation

Step 4: Launch the App

Open Weesper Neon Flow from the Start menu. Your app should launch normally, and you should see:

• ✅ Your configured hotkey
• ✅ Your selected language and transcription model
• ✅ Your license activation state (trial or paid)
• ✅ Your transcription history

Everything is preserved because your personal data was never removed.

Verify You Are on 1.5.0

Once the app is running, you can verify the installed version:

1. Right-click the Weesper Neon Flow icon in the Windows system tray
2. Click About
3. The About dialog will display Version 1.5.0

What About the Fix?

A fixed 1.5.2 release is already in preparation and will ship in the coming days. When it is available, the built-in auto-updater on your 1.5.0 installation will offer the update automatically on next launch. You do not need to check manually or revisit this page.

Still Having Issues?

If after reinstalling you experience any of the following:

• Your license is not recognized
• Your settings or hotkey are reset to defaults
• The app still crashes at launch or during dictation
• Any other unexpected behavior

Please contact our support team with:

• A screenshot of the issue
• Your Windows version (press Win + R, type winver, press Enter, and screenshot the dialog)
• A short description of when the problem happens (at startup, when pressing the hotkey, during transcription, etc.)

We monitor support email closely and will respond quickly.

Thank You

We are sincerely sorry for the disruption. Issues like this are rare, and your patience and feedback help us ship better releases. Thank you for being a Weesper Neon Flow user.
