 Failed to open a session for the VM Win 7 exit code 1;

 RTR3Init failed with rc=-1912(rc=1912)

After running dpkg --list | grep virtualbox:

ii  virtualbox                             4.1.12-dfsg-2ubuntu0.2                  x86 virtualization solution - base binaries

Any help is appreciated…

You seem to have two separate versions of VirtualBox installed!

I would recommend that you fully uninstall all versions of VirtualBox:

sudo apt-get autoremove 'virtualbox*'

Then reinstall directly from Oracle. Go to the VB download page, scroll down to "Debian-based Linux distributions", and follow the instructions.

Then try again.

By the way, you don't need to use grep with dpkg. Here is a nicer alternative to your command:

dpkg --list 'virtualbox*'
