“The version does not support this version of the file format” in Hyper-V Manager

While building a lab environment in Hyper-V, the following error occurred when I tried to start a VM with a preconfigured VHD from the Microsoft website:

“Win2012-DC1” failed to start.

Microsoft Emulated IDE Controller (Instance ID x) Failed to Power on with Error ‘The version does not support this version of the file format’.

Failed to open attachment …

Microsoft Emulated IDE Controller (Instance ID x) Failed to Power on with Error The version does not support this version of the file format

The solution is easy: make a copy of the VHD file, remove the original VHD from the VM and then attach the copy to the VM.

Genius.

I had the same issue and this helped.

I downloaded 2k12R2.vhd and had it in my downloads folder.

I created a new folder “VHD” on the C:\ root and copied the vhd in there

I went into Hyper-V and changed the path to the new folder

I powered up and it worked.

6 years later and still work this solution, just a copy and paste.
I did a AWS EC2 export and did use rclone to transfer straight to destination folder and got this error. Solution, just copy to another folder using CRTL+C and CTRL+V.

Damn!
Thank you. It helped.
Though, don’t understand why copying a .vhd to the same location (just a “- copy” different .vhd) made it run on a virtual computer.
Thanks a bunch.
