How do I remove an old version of WinPcap?
I resolved this issue on Windows 7 x64 by:
- opening a command prompt as administrator (Win+R > cmd > Enter)
- navigate to
\windows\syswow64 - delete
Packet.dll - reboot
- Install new version of Winpcap
While I never found a way to remove the old WinpCap my colleague suggested I boot up in safe mode in order to stop the mystery program from using it. Although I still got a warning that an old version was unable to be removed (and do I want to continue with the install?) the installation this time was successful.
So if you find yourself in this dilemma a possible workaround is to boot up in safe mode and install from there.
When I uninstalled some Netgear Wireless Adapter software, packet.dll was removed, enabling me to successfully install WinPcap.
