The original WinPcap DLL, wpcap.dll is built by VS 2005, I have updated it to VS 2010 using VS automatic conversion wizard without changing one line of code. But when I launched Wireshark on Win8.1 x64, I encountered an app crash error:

I have updated Packet.dll from VS 2005 to VS 2010 without problem. (If I use VS 2005 version wpcap.dll and VS 2010 version Packet.dll, it works fine) So it can't be lacking C run-time issue. I don't know what's wrong with it?
