EasyWorship 2009 Build 19 was designed to use SQL CE 3.5. Windows 10 (specifically versions 1809 and later, including 21H2, 22H2, and Windows 11) deprecated several legacy API calls that SQL CE 3.5 relied upon. Furthermore, Windows 10’s enhanced security features—specifically and Protected Processes —block the older rendering engine that EasyWorship uses to output to secondary projectors.
