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.

I have to lol but yes as simple as it looks this was the solution to this issue that I was dealing with for the last 45 minutes.
Thanks
wow, never seen a solution like that! Thanks!
Incredible that it is so simple. Thank you.
error messages that make no sense and the simple solutions 🙂
Thank you, after spending 1 hour looking for a workaround, this is the best answer!!
Thank you – no idea WHY this works, but I guess that doesn’t matter.
Whow, incredibly stupid fix!
I love stupid fixes 😀
Increible … vaya solucion … jajajajajaja … funciono!!!
Hello folks,
The issue is that the file is created as a sparse file, and Hyper-V does not like that. An easy solution is copying the file, but that takes some time. There’s another way:
Unblock the file if it’s blocked (right-click file, Properties, click ‘Unblock’ followed by OK/Apply).
Run these commands in an administrative command prompt:
set file=D:\path\to\yourfile.iso
attrib -R “%file%”
fsutil sparse queryflag “%file%”
fsutil sparse setflag “%file%” 0
Afterwards, the VM should boot from the ISO successfully. Good luck and enjoy! Please let us know if this helped!
