Run the installer
Double-click ClassicMahjongPC.exe. If Windows shows a blue "Windows protected your PC" screen, that's SmartScreen — see the note below.
How to get past the Windows SmartScreen warning
SmartScreen warns about apps it hasn't seen many times yet — new releases trigger it. Here's what to do:
- When the blue "Windows protected your PC" screen appears, click More info (small text below the warning).
- Check the app name shows Classic Mahjong PC and the publisher name matches what's shown on this page.
- If both match, click Run anyway.
If the publisher name doesn't match, don't run it — contact us instead.
