The VirtualBox 4.2.12 on Ubuntu 12.04 was running fine till I needed to install guest additon. After its installation:

 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...

Thanks...

PLease clarify: for which version of virtualbox and how did you install the guest additions? Which version do you want to run (there is no 4.2.12)? DPKG tells us you have an old version 4.1.12 installed but 4.2.6 removed. How did you install virtualbox? Please also name tne architecture of the host (amd64 i386?). –  Takkat Feb 2 '13 at 15:19

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*'
