Hyper-V – Application error while trying to change status

If you ever have problems starting your Hyper-V VM’s , it may well be that you have copied or moved parts or the entire Hyper-V VM directory or renamed the directory. Then such an error message can appear:

Application error while trying to check the status of ???? to change.

Error starting … ..

Microsoft Emulated IDE Controller (Instance ID: ……): Error when switching on: General “access denied” error.

The account “IDE / ATAPI” does not have sufficient permissions to open the system “… ..” error (0x80070005).

The Hyper-V Virtual Machine Management Service account does not have sufficient permissions to open the “…” attachment. Error: General “access denied” error.

Hyper-V application error access denied startup error

Fixed Hyper-V error 0x80070005

The problem is with the existing .VHD or VHDX files. The hypervisor cannot get explicit access to these VHD files and therefore reports this error code for this reason. You can fix this relatively easily by doing the following.

Please open the properties of the virtual machine and remove the VHD files from the VM. Please note the exact order of the configured hard drives so that you can set them up again afterwards. If you then click on ” Apply “, you can add the previously removed VHD or VHDX files to the virtual machine again. Finally, activate the changes again via “Apply”.

Then you can restart the VM and the described error code or error message should no longer occur. If you still have problems with this Hyper-V error code , please leave a comment at the end of this article, we will then try to help you.
