During install of VM VirtualBox 5.1.18 on Windows 10 I get an error when installing to another drive (D:), but on my main Windows harddrive (C:) it works just fine. I've tried installing other programs but they get interrupted as well. When the installer tries to make a directory thats when the error occurs, even while being run as administrator. I tried editing the permissions for the root of drive D & applying the permissions to subfolders but the installer is still showing the same error. How can I successfully install programs to this other drive?
Also, this is a recent install of Windows, been using it for a month or so.

Heres a few methods I've tried so far that haven't worked:
