Not understanding an install error

I get this on several files:

[11/13/2014 14:02:00] Success Install archive file: C:\Dillo\OLEAUT32.DLL
[11/13/2014 14:02:05] Error Register COM file: C:\Dillo\OLEAUT32.DLL - System Error # 0 (3)
[11/13/2014 14:02:05] Notice Register COM failure reason: Error 0x80070005: Access is denied.

I am running this on a new W7 virtual machine and as admin.
