Hi list, 

After several months, I retried updating wpcap project from VS 2005 to VS 2010) and encountered the same issue, under Wireshark 2.0.1 x64, Win10 x64.

The Wireshark UI said "Child dumpcap process died: Access violation". I don't know what this means, because I have used Administrator privilege to launch Wireshark.

I have just attached the x64 version wpcap.dll in this mail, you can just substitute it with the original WinPcap/Npcap version in C:\Windows\System32. Then launch Wireshark and you will see the crash. Hope that any one can see what's wrong with it here.

Hi list,

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?
