wrong license key?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi,

we have updated from version 1312 to 1711.We ordered the update and installed it.
We got a license key.
We set name and license key in foxit_quick_pdf_library_1711_en.exe

The example:

procedure TForm1.Button1Click(Sender: TObject);
var
  PDFLibrary: TDebenuPDFLibrary1711;
  UnlockResult: Integer;
begin
  PDFLibrary := TDebenuPDFLibrary1711.Create;
  try
    UnlockResult := PDFLibrary.UnlockKey(Edit1.Text);
    Label1.Caption := PDFLibrary.LicenseInfo;
    if UnlockResult = 1 then
    begin
      PDFLibrary.DrawText(100, 500, 'Hello from Delphi');
      PDFLibrary.SaveToFile('C:\Temp\HelloFromDelphi.pdf');
    end
    else
    begin
      ShowMessage('Invalid license key');
    end;
  finally
    PDFLibrary.Free;
  end;
end;

always shows "invalid license key"

Is it not possible to update from 1312 to 1711 or what is wrong?

Help please!

Stefan

	Hi Stefan, directly after UnlockKey you should use LastErrorCode: https://www.debenu.com/docs/pdf_library_reference/LastErrorCode.php You've bought the update and got additionally a license key... Is it a test key or the key for the full version? Did you try the license key from your old 13.12-version, too?
	Cheers, Ingo
