When I start the VirtualBox program I get the message:
Failed to create the VirtualBox Com object
The application will now terminate.
Callee RC: E_ACCESSDENIED (0x80070005)
This didn't happen for about two weeks after installation. However, now it is consistent.
Note that if I invoke the program using administrator priviges then the failure does not occur. Why does it suddenly need adminstrator privieges to execute?
