	Hi Temer! The problem could be your first 32-bit-installation/-dll. Before using the 64-bit-dll you should completely (registry-entries...) remove the 32-bit-dll. A common problem: You know that 32-bit-dlls should be on 64-bit-system in syswow64 and 64-bit-dlls in system32? Cheers and welcome here, Ingo

	Hi Ingo, I know that. The DLL is in a folder, just my Aplication use this DLL (version 9.11 ....), When the software build in 32bit I use the DLL for 32bit, and is the same for 64bit. The problem is render the slide in a device context, in 64bit doesnt show nothing, but in 32bit work well. Thanks. Temer
