Yes, that's correct! There are Hyper-V keys missing (That's why I was seeing Hyper V errors). We are now replacing them, but I don't have the one you mention. I'll check my other VMs and machines I have access to and get back to you.
After we fix the keys, we'll likely have to fix the versions, so the machine knows what to look for. After the versions present are fixed, we move on to the actual files (payloads)...
