Hi, Alexey.

What does your registry key have for this driver?

I have a self-built VBox installed on two computers with Windows 7, both UEFI, 
never had similar problems. The only real difference is, I'm using a 
no-hardening build. Maybe something is injected that VB does not like?.. 
Although I doubt it would show "cannot find file" in this case.

And, I know it's silly, but did you make sure to see the real system32, not the 
substituted syswow64? Even experienced users forget about this sometimes.
