How to find out the current locally installed version of WinPCap?

[Ben Stover]

I somehow guess that WinPCap is already installed on a certain local computer (under WinXP+SP3).

How can I find out if WinPCap is installed and if yes which version?

Is WinPCap implemented as a DLL or as a SYS driver?

Ben

You might try the registry:

C:\>reg query
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\WinPcapInst

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\WinPcapInst
DisplayName REG_SZ WinPcap 4.1 beta4
UninstallString REG_SZ C:\Program Files\WinPcap\uninstall.exe
Publisher REG_SZ CACE Technologies
URLInfoAbout REG_SZ http://www.cacetech.com
URLUpdateInfo REG_SZ http://www.winpcap.org
VersionMajor REG_SZ 4
VersionMinor REG_SZ 1
DisplayVersion REG_SZ 4.1.0.1237

Wireshark's installer uses UninstallString, DisplayName, and DisplayVersion:
