Hi there.

As part of OEM usage our contact is attempting to silent install 0.9983 which fails (this way allows npcap to show as installed in Apps/Features, yet the setipapi.dev log still shows a cert install failure). As part of troubleshooting we've moved to the latest version 0.9997 via the GUI installer to attempt forward fixing and troubleshooting. As a baseline install of 0.9997 via installer .exe was also attempted on a new, previously not installed host.

The installation fails on existing or new servers and provides exception error and continued events in setupapi.dev. log. The client is running on Win Server 2012 R2 with admin rights.
