Error 0x8007007E on uninstall of Npcap Packet Driver

Open JanB1 opened this issue 1 year ago • 2 comments

Describe the bug After failing to be able to install Npcap 1.80 I now have a broken installation of Npcap. I tried to uninstall the Npcap Packet Driver on my network card, but this failed with the same error code I also got during the failed installation of Npcap 1.80.

To Reproduce Steps to reproduce the behavior:

  1. Go to adapter settings
  2. Right-Click on your network adapter and click on "properties"
  3. From the list "this connection uses the following elements" select Npcap Packet Driver
  4. On the bottom choose "Uninstall"
  5. Uninstall fails with error 0x8007007E, see Screenshot

Expected behavior Uninstall of Npcap Driver

Diagnostic information

  • Windows version Win 10 Pro 22Hs Build 19045.5011
  • Output of DiagReport: none, as application is uninstalled
  • Installation log: install.log

Additional context Additionaly, since the failed Install, I get a BSOD with error "KERNEL_MODE_HEAP_CORRUPTION" on startup if I login before the network connection is established. Also, before this the network connection was always established quite fast on startup, now it takes longer.

I'm sorry to hear you've had trouble installing and removing Npcap. The error 0x8007007e is ERROR_MOD_NOT_FOUND, which users have reported may be related to an incomplete VMware Workstation uninstall. See https://github.com/nmap/npcap/issues/135#issuecomment-2355869064 for a potential fix. Please let us know if this resolves your issue. If not, please also provide the SetupAPI.dev.log and NPFInstall.log files for us to further diagnose.

I also saw #135 as I was first trying to install the newest Npcap version and encountered the error described in #135. I tried deleting the registry key, but to no avail. Then I found a this comment thread on Reddit and tried to uninstall the leftover Npcap Packet driver, which is when I encountered the error from my report.

I already attached the install log in my report, if that's the correct one, and the SetupAPI.dev.log you'll find attached to this comment. setupapi.dev.log
