	Hi Stefan, a code snippet to check your syntax would be great ;-) What's the meaning of "i try to create debenu"? There are different versions of the library. For windows, android, and so on ... Due to this i can imagine that each license key is only valid for one library version?
	Cheers, Ingo

	Here a few lines of code: {$IFDEF ANDROID} SharedObjectFileName := TPath.Combine(TPath.GetDocumentsPath, 'libDebenuPDFLibraryAndroidArm1311.so'); if fileexists(SharedObjectFileName) = False then Showmessage('*.SO-File missing!'); PDFLibrary := TDebenuPDFLibraryCPAndroidDelphi1311.Create (SharedObjectFileName); key := GetPDFKey(); //geting my key, stored in a special path {$ENDIF} {$IFDEF MSWINDOWS} PDFLibrary := TDebenuPDFLibrary1311.Create; key := GetPDFKey(); {$ENDIF} UnlockResult := PDFLibrary.UnlockKey(key); if UnlockResult <> 1 then Showmessage('Invalid License Key !'); At the special device UnlockResult = 0 and i don't know why :-((( This code works with all Windows and Android devices, only the ode will not work! The user has set his Tablet to factory default and the problem is always ... Ciao Stefan Edited by skoschke - 31 Jan 17 at 12:52PM

	Hi, in the meantime i have moved on and found that the library is not loaded! Even when the library is not loaded, unlockkey result = 0 (like bad license key). What could be the cause? Ciao Stefan Edited by skoschke - 02 Feb 17 at 11:14AM

	Hi Stefan, you should check the resulting value from loadfromfile. There'll be the first error. Using unlock will only raise a following error. Using unlock without loading returns with 0 (nothing) - this should be normal behavior?
	Cheers, Ingo
