Hi,

I developed an PDF viewer in C++, worked well using DLL in 32bits, but when I build the software in 64bits and use the DLL 64, the render doesnt show nothing. 
Windows 8.

Someone Can help me?

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
