Then download the latest version of Npcap and install it.Copyright 1998-2019 Gerald Combs and contributors. I suggest you uninstall WinPcap and Npcap from Control Panel, if it reports either of them, and then remove any Npcap directories in C:\WIndows\System32 and C:\Windows\SysWOW64. On a 64-bit version of Windows, the installer also installs libraries in C:\Windows\SysWOW64\Npcap, for the benefit of 32-bit programs. Please close all the WinPcap-based applications and run the installer again. There's wpcap.dll, which is the DLL that implements the Npcap API (libpcap API, with UN*X-specific APIs removed, Windows-specific APIs added, and some additional APIs), and packet.dll, which is used by wpcap.dll to communicate with the NPF driver that Npcap installs to do packet capture. 13 When installing WinPcap 4.1.2 on Windows 7 I receive the following message 'A previous version of WinPcap has been detected on this system and cannot be removed because in use by another application. If not installed in WinPcap compatible mode, the libraries are installed in C:\Windows\System32\Npcap. That option is not necessary for Wireshark Wireshark will work OK with WinPcap (assuming WinPcap itself works on your version of Windows), Npcap installed in WinPcap compatible mode, or Npcap installed not in WinPcap compatible mode. If compatibility mode is not selected, Npcap can coexist alongside WinPcap applications which only know about WinPcap will continue using that, while other applications can choose to use the newer and faster Npcap driver instead. I have installed Npcap 1.60 and from the system32 directory there is already wpcap.dll, why it still prompt this error Does it mean npcap needs to build one ARM64EC wpcap. WinPcap compatibility: For applications that don't yet make use of Npcap's advanced features, Npcap can be installed in “WinPcap Compatible Mode.” This will replace any existing WinPcap installation. I installed win11 with my Surface ProX device, and when starting wireshark 圆4 (3.6.5) it prompts 'Unable to load Npcap or Winpcap (wpcap.dll)'.The Npcap installer has an option for "WinPcap Compatible Mode". it's actually in syswow64 folder (also packet DLL which looks related). I noticed that when i run the NPCAP installer it will search for wpcap DLL in "c/System32/wpcap.dll" which is not there. WinPcap may have some issues with newer versions of Windows (such as Windows 10), and Npcap should address those issues. I understand that NPCAP is needed to fix the compatibility issue. What is "wpcap"? If it's WinPcap, it is compatible with Wireshark, as is Npcap.
