Half a year ago I wrote a blog post about issues when mounting an ISO downloaded from TechNet. This error is related and its the error you will get in Hyper-V when starting the virtual machine from the a mounted ISO:
“Synthetic SCSI Controller (Instance ID xxx): Failed to Power on with Error ‘The version does not support this version of the file format’.
The solution to this problem is to make a copy of the ISO file and then mount the copy instead.
If you want to learn how to create a Hyper-V VM from an ISO using Powershell, read this blog post on the Altaro website by Jefferey Hicks.
