I just built VBox and it installed successfully, however when I try to 
run it I get the following failure in a dialog box:



Failed to create the VirtualBox COM object.
The application will now terminate.

Callee RC:
NS_ERROR_ABORT (0x80004004)


Is there any more info I can provide to help troubleshoot this problem?

Thanks in advance for any help.
