Hi,

I can't launch the installation of WinCap, it tells me "A newer version of WinPcap (internal version 5.1.79.117) is already installed on this machine. The installation will be aborted.". I uninstalled Npcap, enabled comptability mode, tried to rename wpcap.dll wpcap.dll.old but it tells me that it's already running so i enabled S mode then network but it didn't work.

I would be very glad if someone could help me.
