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.

Research direction

Start by reproducing the newest installer failure on Windows 10 and review the provided installer log, especially the step after “Stopping the npcap driver.” Trace the installation path for C:\Program Files\Npcap and determine why it aborts; done means the installer completes successfully without manual cleanup.
