LeadTools version 17.0.4.0 fails on 64 wpf application

I'am trying to develop a wpf OCR application that target x64 and use your 32bit dlls
But i get this error:
(Note: I don't have this problem when i target w32 and use your win32 dll version)

If you want to build your application as 64-bit, you have to use the 64-bit version of LEADTOOLS DLLs.
Bu if you want to use LEADTOOLS .Net win32 DLLs on a 64-bit machine, you should NOT build your application to Any CPU or 64-bit. You must specifically build for 32-bit (x86 CPU). The resulting 32-bit EXE can be deployed on both 32-bit and 64-bit operating systems.
