On 64-bit WIndows 7 I installed VirtualBox-4.3.14-95030-Win on top of VirtualBox-4.3.10-93012-Win without an uninstall. I received the error below when running it then. I uninstalled, rebooted and reinstalled but still receive the same error.

VirtualBox - Error In supR3HardenedWinVerifyProcess

Failed to verify process integrity: More than one thread in process (rc=-5640)
Please try reinstalling VirtualBox

Any ideas?
