Kennt sich jemand mit OLE bezüglich Microsoft Word aus?
Ich versuche eine .DOCX per OLE als .RTF speichern zu lassen. Das Laden funktioniert, das Speichern aber nicht.
Ich verwende Lazarus v2.0.10 auf Windows 10 64bit mit Office 2021.
Der Fehler tritt immer bei Doc.SaveAs2() auf, egal welche Parameter ich bisher übergeben habe.
Danke und Grüße, Jörg
