Das wars - vielen Dank für den Tipp!
Es gibt einen Eintrag im QP.
Man muss das statische Linken erzwingen durch einbinden der "FireDAC.Phys.SQLiteWrapper.Stat":
Zitat:
Starting from 10.4 FireDAC SQLite driver supports static and dynamic linkage of SQLite3 engine. Only statically linked SQLite3 engine supports encryption. If somehow dynamically linked engine is used and application requests encryption of SQLite database, then error "Capability is not supported" is returned.
...
2) To use statically linked engine, your application must include FireDAC.Phys.SQLiteWrapper.Stat
unit into uses clause. This
unit will be added automatically by
IDE for new/modified forms/modules which has TFDConnection configured to use FireDAC SQLite driver. Or you can add this
unit by hands
Jetzt läufts (kA warum es bei 10.3 auch ohne die
unit ging, aber egal)
