Windows installation help

Our Windows installer is not code-signed with an EV certificate. Windows or your browser may block it. Pick the scenario that matches what you see, then follow the steps.

Smart App Control

Windows 11 may block unsigned apps with Smart App Control (SAC). You may need to turn it off before installing.

  1. 1Open Settings → Privacy & security → Windows Security.
  2. 2Click Open Windows Security → App & browser control → Smart App Control settings.
  3. 3Select Off, confirm the warning, then restart your PC when prompted.
  4. 4After restart, run the downloaded installer again.
  5. 5Note: turning SAC off may require reinstalling Windows to turn it back on. Only disable if you trust this installer.

SmartScreen warning

When running the installer, Windows may show "Windows protected your PC" or "unrecognized app".

  1. 1Double-click the downloaded .exe installer.
  2. 2On the blue SmartScreen dialog, click More info (not Run).
  3. 3Click Run anyway to continue installation.
  4. 4If prompted by User Account Control (UAC), click Yes to allow changes.

Browser blocked download

Edge or Chrome may remove or warn about unsigned .exe downloads before you can run them.

  1. 1Open the browser downloads page: Edge/Chrome press Ctrl+J (Cmd+Shift+J on Mac).
  2. 2Edge: click ⋯ next to the file → Keep. If blocked again, Show more → Keep anyway.
  3. 3Chrome: click Keep or Restore, then Keep dangerous file if warned.
  4. 4Open the saved file from your Downloads folder and continue with the SmartScreen tab if needed.

Unblock file

Files downloaded from the internet may be marked as blocked (Mark of the Web) and fail to run silently.

  1. 1In File Explorer, right-click the installer → Properties.
  2. 2On the General tab, check Unblock at the bottom if shown → Apply → OK.
  3. 3Double-click the installer again. Right-click → Run as administrator if it still won't start.
