Thread-topic: help Windows PV Drivers and Windows Server 2025

This concerns the installation of the Windows PV Drivers on Windows Server 2025.

When running "dpinst.exe", the installation fails with the message "Install failed".

The affected driver version is:
DriverVer=07/13/2023,9.1.0.1

I am currently using an older version that works correctly:
DriverVer=12/05/2019,9.0.0.2

Kind regards, Henry Bakker.
