Frequently asked questions (FAQ)
Windows shows an "unrecognised app" warning.
The program is safe to install. This is an early release and code signing is still being registered, so Windows blocks it temporarily. [How to install] Click [More info] in the warning dialog, then press the [Run anyway] button that appears.


Is there a macOS or Linux build?
Bible OnAir currently supports Windows only. Support for further platforms is under review.
My projector is not in the monitor list.
Check whether the display setting is set to "Duplicate". In duplicate mode Windows sees a single monitor, so the projector does not appear in the list. Right-click the desktop ➔ [Display settings], or press Win + P, and switch the mode to [Extend].
