Windows VirtIO Drivers Upgrade (error)

[alexkenon]

Good day.

Installed:
OS: MS Windows Server 2016 Standard. Latest updates installed.
Windows VirtIO Drivers: virtio-win-0.1.266

Trying to update Windows VirtIO Drivers to 0.1.271, but it gives an error. I've tried mounting the CD-ROM (iso image) and simply running virtio-win-guest-tools.exe, but it doesn't work. Tested on several virtual machines, still the same.

Never had any problems with Windows VirtiO Drivers updating before. Always updated without any problems.

What are the options for a solution?

Not sure why you would need to update the drivers on a working (?) system, all the time.

There is a newer 0.1.285 version available.

I believe this matches your experience.

Maybe see here also.
