Could not load the Host USB Proxy Service since v4.1.0

Reported by: kh151 Owned by:
Priority: major Component: USB
Version: VirtualBox 4.1.0 Keywords:
Cc: Guest type: Windows
Host type: Windows


On going into settings of a guest that has USB switched on, I get an error message as below.

Failed to access the USB subsystem.

Could not load the Host USB Proxy Service
(VERR_FILE_NOT_FOUND). The service might not be
installed on the host computer.

Result Code: 
E_FAIL (0x00004005)
IHost {dab4a2b8-c735-4f08-94fc-9bec84182e2f}
IMachine {5eaa9319-62fc-4b0a-843c-0cb1940f8a91}

Using Windows 7 64-bit Home Premium (fully updated), Asus P5K motherboard, Intel Q6600, 4GB Corsair XMS2 - let me know if any other hardware specs needed.

I've updated through all previous versions of Virtualbox in the past and this is the first version to give me this error. Have tried doing a repair install, restarting, etc. I did also update the Extension Pack for the new version but have also tried removing and reinstalling that too.

This issue seems to happen only on Vista (mostly x64) machines. Would really like it to be resolved :)
