Microsoft doesn't think you know how to use your own computer

When you download or run ChronAlert, Windows may pop a blue "Windows protected your PC" box, or your browser may mutter that the file "isn't commonly downloaded." That is SmartScreen, and it flags every app that is not signed with a pricey certificate. It is complaining about a missing paid signature, not anything wrong with ChronAlert. The big vendors rent that badge from Microsoft every year; we would rather spend it on the app. What you download is the exact installer built from our own source, with nothing bundled and nothing phoning home.

If your browser blocks the download

  • Chrome / Edge: on the download, click the … (or the warning), then Keep → Keep anyway.

When you run the installer

  1. Double-click ChronAlert-Setup.exe.
  2. See "Windows protected your PC"? Click More info.
  3. Click Run anyway. Done.

Optional: right-click the file → Properties → tick Unblock → OK, then run it. Prefer no gatekeeper at all? The Linux build has none of this.

On Windows, run the installer; on Linux, make the AppImage executable and run it. ChronAlert then starts serving on your machine. To view from another screen, browse to that machine's address on port 8420. See the Install Guide for setup and activation. For everything ChronAlert can do, read the User Manual.
