I am using Windows 7 Home Edition 64-bit and installed VirtualBox version 4.3.28 r 100309.  When I use the VM of ubermix on the version 2.0 file, the VM did not start properly and terminated with the following message:

Failed to open a session for the virtual machine Ubermix 2.0.

No error info.

Result Code: RPC_S_SERVER_UNAVAILABLE 0x800706BA (0x800706BA)
Component: ProgressProxy
Interface: IProgress {c20238e4-3221-4d3f-8891-81ce92d9f913}

Can someone offer any pointer to get around this issue?  Thanks!

Best Regards,
Stephen Lee

Sounds like Virtualization is disabled in the BIOS of your machine. Am guessing it's HP, so what you would do is reboot and press the ESC key repeatedly as it turns on until the BIOS menu appears. Look for a BIOS settings option, then for a virtualization option.

If not HP, consult your manufacturer documentation for instructions on getting into the BIOS setup.
