Hello. After updating to 14.2 and IEVision 8.1.6, the error
“A required library file (ievision.dll) has not been initialized or is outdated (Version expected: 8.1.6.0)”.

...
LWidth := LPDF.PageInfo[i].Size.X * (LPDF.PageInfo[i].UserUnit / 72);
LPPI := round(LBmp.Width / LWidth);
LIEBmp.Assign(LBmp);
LIEImg := LIEBmp.GetIEVisionImage; // => Exception
LIEImg.setDPI(LPPI);
LPDFGen.addPage(LIEImg, ievPDFImgFmt_AUTO);

The error did not occur with version 13.6 and IEVision 8.1.4. I replaced the DLL in the program directory; it is version 8.1.6.0.

Thanks, Harald

Hi Harald

I suspect an old version is lurking on the system there. Please post/send your DLL loading log:

Note: You can also check the version of DLL files, by right-clicking them and viewing the properties.

Hello Nigel. So far, I have only initialized the DLL with
IEVisionSetSerialNumber(Cfg.IEVisionMail, Cfg.IEVisionSN);

It was interesting that it worked when I additional called 
ShowMessage( IEGlobalSettings().ImageEnVersion.Status );


I now use
if not (iepiIEVision in IEGlobalSettings.ActivePlugIns) then
  IEGlobalSettings.RegisterPlugIns([iepiIEVision], Cfg.IEVisionMail, Cfg.IEVisionSN);

to initialize the DLL.

Thanks, Harald

Hi Harald

Yes, you need to explicitly call RegisterPlugIns() or IEVisionAvailable() to register the DLL.

Our preferred method is:

procedure TMainForm.FormCreate(Sender: TObject);
const
  User_Email  = '...';
  User_Serial = '...';
begin
  IEGlobalSettings().RegisterPlugIns([iepiIEVision], User_Email, User_Serial );
  if not ( iepiIEVision in IEGlobalSettings().ActivePlugIns ) then
    ShowMessage( 'This application requires the ievision.dll plug-in, v' + IEVC_EXPECTED_LIBRARY_VERSION +'.' );
end;
