很久没使用wireshark后重新打开就出现警告：

The NPF driver isn’t running. You may have trouble capturing or
listing interfaces.

点击菜单栏caption，准备启动的时候，又显示警告框，直接不给操作：

Unable to load WinPcap (wpcap.dll); Wireshark will not be able to capture

以下wireshark的官方网站的解决方案:

Q:

I used wireshark, Version 1.0.4 (SVN Rev 26501), in windows xp and it has
worked fine before, but recently it has problem whenever I clicked the "Show
the capture options … " tab.

The attached is the screenshots to replicate the problem. The popup screen
with the message "Unable to load WinPcap (wpcap.dll); Wireshark will
not be able to capture packets … " shows the problem when click the
"Show the capture options … " tab.

It will be much appreciated if anyone can help with this.

A:

Obviously something went wrong, but the question is What…

Did you check if wpcap.dll is still in the folder C:\WINDOWS\system32
If not, download WinPcap and install it again. //如果,在此目录没找到dll,重装

If so, maybe the file is corrupt. //如果找到,也可能这个文件损坏了
Go to Settings -> Control Panel -> Add or Remove Programs to uninstall WinPcap. //去控制面板卸载掉,用下面连接下载,重新安装
Next download WinPcap and install it again.

You can download WinPcap 4.0.2 or WinPcap 4.1 beta4 here:
http://www.winpcap.org/install/default.htm
Both versions work fine.

也就是说：

找一下目录C:\WINDOWS\system32下是否有wpcap.dll

如果在此目录没找到dll，重装；

如果找到，可能这个文件损坏了，到控制面板卸载掉，用下面连接下载，重新安装

http://www.winpcap.org/install/default.htm

发现首页显示：“WinPcap已停止开发。我们建议Npcap。”

因此，我们直接到npcap下（下图展示的是win10的）下载就可以了：https://nmap.org/npcap/#download

顺便贴一下npcap的首页，详细信心可以适当浏览一下https://nmap.org/npcap/

下载完成后，得到一个exe可执行文件：
双击执行安装：

当显示选择是否uninstall之前的winpcap时，复选框要记得勾选上，在最后一个选项。

然后就是确认卸载winpcap，点击确认就好了。

到这里就结束了🍗

重新运行wireshark，也可以正常操作了💨

祝好运！加油！
