Description
Hey,
I tried updating my npcap driver by running the newest installer. For some reason the installer fails right on start. I tried manually removing old parts of npcap, such as the service, driver file, dll files but had no success so far. When manually creating the Npcap folder inside ProgramFiles I was able to get the installer log.
