Help · BILL OS

BILL OS will not open, or shows an error window

What to check when BILL OS does not open: the window already open, WebView2 missing, the program restarting itself, and where the logs are.

  • Nothing seems to happen. BILL OS runs only once per computer. Opening it again brings the existing window to the front; check the taskbar.
  • A message about WebView2. BILL OS needs the Microsoft Edge WebView2 Runtime. Connect to the internet and run the setup again, or install WebView2 from Microsoft.
  • A Retry / Close message. BILL OS restarts its own service if it stops unexpectedly. If it cannot, the window says so; choose Retry.
  • After restoring a backup. BILL OS restarts by itself; sign in again.
