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 Yang,

I just gave a test to you dll (have replaced the existing version in C:\windows\System32\ and C:\windows\SysWOW64\ and did not face a crash when running it on Windows 7 x64:

Does it require a reboot of the system?

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?


Cheers,
Yang
