Description

"Hi,

I keep getting this error message every time I try to install Npcap: 'Failed to create the npcap service: 0x8007007e'. It never works, no matter what I do.

I've tried everything:

  • Reinstalling it many times.
  • Turning off Windows Defender / security completely.
  • Downloading and installing the C++ redistributables and other libraries.
  • Running the installer as Administrator every time.
  • Using the latest installer from the official website.

Nothing works. The program refuses to install or run at all.

I'm using Windows 11 Pro, 64 bit

Please help, I'm stuck."
