Installing Wispr Flow on Windows: what to expect from the downloadable installer

Last updated: October 28, 2026

Available on: Windows 10 or 11 (x64 only)

The standard download installs for your user account without administrator permissions, under %LOCALAPPDATA%\WisprFlow. IT-managed, machine-wide installations in Program Files require administrator rights.

How to install Wispr Flow on Windows

The official download can be named WisprFlowInstaller.exe or Wispr Flow Setup-v<version>.exe; both are legitimate.

Warning: Official Windows releases are signed by Wispr AI, Inc., so downloads from wisprflow.ai should not show “Unknown Publisher.” SmartScreen can still show “Windows protected your PC” for a newly published release; continue through this prompt only for an official download.

  1. Download the Windows installer from wisprflow.ai.

  2. Double-click the installer in your Downloads folder.

  3. Wait for installation to finish.

  4. Launch Wispr Flow from the Start menu or desktop shortcut—a new install creates both.

Note: WisprFlowInstaller.exe downloads about 340 MB before setup continues. Its download window can't be cancelled and closes without an error when setup takes over, so closing doesn't confirm installation is complete. Opening that installer again while it's running does nothing.

On a new install, the hub opens with onboarding and keeps opening at launch until onboarding is complete; dictation and the Notetaker become available at that point. Closing the window during onboarding only hides it; reopen Flow to continue where you left off.

Updates refresh the Start menu shortcut and any desktop shortcut you keep, but don't recreate a desktop shortcut you deleted. Uninstalling removes both.

Starting up after installation

Flow enables Launch app at login automatically on the first launch of a new install, without a confirmation dialog. Change it in Settings → System → App settings; the change applies immediately and governs your next Windows sign-in.

Launch app at login

Behavior after onboarding is complete

Enabled

Flow starts in the background at login, and when opened after quitting, without opening the hub.

Disabled

Opening Flow opens the hub.

Click Flow's icon in the Windows system tray to open the hub, or right-click it and select Open Wispr Flow. Closing the hub doesn't quit Flow—it keeps running in the tray.

If Flow doesn't start at login

With Launch app at login enabled, opening Flow refreshes its Windows startup shortcut. Antivirus software or a locked file can block this without an error message, leaving the toggle on but auto-start not working.

  1. Press Win+R.

  2. Enter shell:startup and press Enter to open the Windows Startup folder.

The folder should contain Flow's shortcut. At your next Windows sign-in, Flow should start; if it doesn't, contact support.

If an installation error appears

If Flow shows Unsupported Windows Architecture—“Wispr Flow requires x64 architecture. Please use a compatible Windows device to continue.”—its only button is OK, and dismissing it closes Flow. Re-running the same installer won't resolve this: a compatible x64 Windows device and an x64 build are required.

For any other error:

  1. Record the exact error text, then dismiss the dialog.

  2. Download the installer again from wisprflow.ai if it reported that it couldn't finish installing.

  3. Run the installer again. If the error returns, contact support; otherwise launch Flow from its shortcut.

Download and installer failure messages

WisprFlowInstaller.exe can report “Wispr Flow couldn't finish installing.” with one of these details: “We couldn't reach the download server.”, “The download didn't finish.”, “The downloaded file failed a security check.”, “The installer downloaded but wouldn't start.”, or “Setup ran into an unexpected problem.”

Reinstalling Flow

The standard Windows uninstaller keeps your user data and session, so reinstalling restores your existing settings and skips onboarding. Retained data in %APPDATA%\Wispr Flow includes dictation history, notes, dictionary entries, and Notetaker audio and transcripts.

Removing local data doesn't reset everything to factory defaults: synced preferences return after sign-in. For a completely clean install, contact support for help removing the remaining data before reinstalling.

Still need help?

Contact support if Flow doesn't appear in the Start menu after installation. Include the error message text (if any), your Windows version, device, and what you tried. If support requests logs, they're in %APPDATA%\Wispr Flow\Logs.
