windows 21h1 19043.1052 x64

npcap-1.40.exe /prior_driver=yes fails to. Reinstalling npcap-1.31.exe works. after npcap-1.40.exe /prior_driver=yes deleted my npcap-1.31 driver. While npcap-1.31 works without any issues, npcap-1.40 doesn't install.

Good day,
I have the same result on 3 hosts:

  1. Windows 10 Enterprise LTSC / Version 1809 (OS build 17763.1935) x64 (AMD)
  2. Windows 10 Enterprise LTSC / Version 1809 (OS build 17763.1999) x64 (Intel)
  3. Windows Server 2019 / Version 1809 (OS build 17763.1879) x64 (VM) (Host system: VMware ESXi, 6.5.0 U3, 17477841) / VMware Tools 11.2.1.17243207
    Logs from all 3 hosts:
    AMD_install.log
    AMD_NPFInstall.log
    Intel_install.log
    Intel_NPFInstall.log
    VM_install.log
    VM_NPFInstall.log
    Error when npcap service installing:
    npcap_install_error_01
    And also stucked on aborting:
    npcap_install_error_02

On all hosts used local system admin account. But on VM, also new user with Administrators group rights was created, but with the same installation error result.

Npcap 1.31 work fine on all this hosts.

Thanks everyone! I'm able to reproduce this on one of my Windows 10 virtual machines too. We're investigating the situation now.
