Install Keito for Windows

Keito for Windows puts the timer in your notification area, so you can start and stop work without keeping a browser tab open.

Download Keito for Windows

On a Mac? See Install Keito for Mac. On Linux? See Install Keito for Linux.

The download is a 64-bit installer for Windows 10 and Windows 11. It is signed by OSO DevOps Limited and updates itself after installation. The same installer is what the Microsoft Store delivers.

Requirements

  • Windows 10 or Windows 11, 64-bit (x64).
  • A few hundred megabytes of free disk space.
  • No administrator rights. Keito installs for the current user only.

1. Run the installer

Open Keito-x64-setup.exe from your browser’s downloads list or your Downloads folder.

Windows SmartScreen shows the publisher as OSO DevOps Limited. If it shows “Unknown publisher” instead, do not continue. Delete the file and download it again from the button above.

2. Choose where to install

The installer offers the default location under your user profile:

%LOCALAPPDATA%\Programs\Keito

Keep the default unless your IT team has asked for something else, then click Install. Keito adds a Start menu entry and a desktop shortcut.

3. Sign in

Keito starts when the installer finishes and appears in the notification area at the right of the taskbar. Open it and sign in with the same account you use at app.keito.ai. Sign-in opens in your default browser and returns to the app automatically.

You can enable Launch Keito at login during setup or later in Settings.

Updates

Keito checks for signed updates automatically. You can choose whether updates download in the background and when to install them. Updates are verified against the same OSO DevOps Limited signature before they run.

Uninstall Keito

Open Settings > Apps > Installed apps, find Keito, and choose Uninstall. Removing the Windows app does not delete your Keito workspace or cloud data.

Your local settings and saved sign-in stay in %APPDATA%\Keito so that reinstalling picks up where you left off. Delete that folder if you want them gone too.

For IT teams

This section covers unattended installation for device management tools such as Microsoft Intune, and is the reference the Microsoft Store uses for the Keito installer.

Silent install

Keito-x64-setup.exe /S

Installs for the current user under %LOCALAPPDATA%\Programs\Keito with no prompts and does not start Keito afterwards. Add --force-run to start it when the install finishes, and /D=C:\Path\To\Keito as the last parameter to choose a different folder. The /D value must not be quoted, even if it contains spaces.

Keito-x64-setup.exe /S --force-run

The installer does not require or request elevation. If it is run from an elevated or SYSTEM context, it installs for that account rather than the signed-in user, so run it in the user context.

Silent uninstall

"%LOCALAPPDATA%\Programs\Keito\Uninstall Keito.exe" /S

Also recorded in the registry as QuietUninstallString under HKCU\Software\Microsoft\Windows\CurrentVersion\Uninstall\ed594080-5e03-58a3-ae89-ad317089179b, together with DisplayVersion, InstallLocation, InstallDate, and the support URL. Uninstalling keeps %APPDATA%\Keito; remove it separately if you need a clean slate.

Installer exit codes

Code Meaning What to do
0 Installation or uninstallation completed. Nothing.
1 The person cancelled the assisted installer. Not produced by a silent (/S) install. Run it again.
2 The installer stopped itself before or during installation. Causes: Windows is 32-bit or older than Windows 10, another copy of the installer was already running, a running Keito could not be closed, the package could not be unpacked, or an existing installation could not be removed or renamed. Wait for any other installer to finish, quit Keito, check the Windows version and architecture, then run the installer again. If it repeats, run the silent uninstall above, remove %LOCALAPPDATA%\Programs\Keito if it remains, and install again.
6710886 (0x666666) Internal handshake between installer processes when elevation was requested and not granted. Not expected for Keito, which never requests elevation. Run the installer as a standard user without elevation.

Any other value indicates the installer was terminated by Windows or by a management tool before it returned. Rerun it and, if it repeats, contact Keito support with the exit code and the Windows version.

Verifying the download

Each release publishes a SHA256SUMS-windows.txt alongside the installer on the releases page. To check the file you downloaded:

certutil -hashfile Keito-x64-setup.exe SHA256

The installer is signed with Authenticode. To confirm the signature in PowerShell:

Get-AuthenticodeSignature .\Keito-x64-setup.exe | Format-List Status, SignerCertificate

Status must be Valid and the signer must be OSO DevOps Limited.

If Windows will not open Keito

Do not continue past a SmartScreen warning that names an unknown publisher or a Windows Defender warning about the file.

  1. Delete that copy of the installer.
  2. Download it again using the button at the top of this guide.
  3. Confirm SmartScreen names OSO DevOps Limited as the publisher.
  4. If the warning continues, contact Keito support and include a screenshot.
