Description of problem:

virtio-win-guest-tools can not install fwcfg driver on Win2012.

If we install the fwcfg driver via "Device Manager"(update driver software) and then uninstall the fwcfg driver with the installer, it will also fail.

Version-Release number of selected component (if applicable):
virtio-win-1.9.30-0.el9_1.iso
kernel-5.14.0-70.13.1.el9_0.x86_64
qemu-kvm-6.2.0-11.el9_0.2.x86_64
seabios-bin-1.15.0-1.el9.noarch
