i solved the problem for installation in windows 10 post anniversary update.
The problem is in kdcom.dll, the owner is TrustedInstaller not admin, and admin has no privileges to replace delete or change that file, manually or using VKD.
You need open the properties of that file and change the owner to admin
Windows 7/8/10 – How to Delete Files Protected by TrustedInstaller
that link is for windows 7 is very similar, not exactly but is the idea, changing the owner to admin, and giving to admin full control to modify, delete, change the dll, yo can run the VKD installer and works replacing kdcom.dll.
next from a admin console
BCDEDIT /dbgsettings serial
restart and press f8 for disable driver signature and will work.
