VirtualBox Critical Error – Looking for Solution

Hello Ney,

To resolve the Virtual Critical Error, you will need to try the following workarounds:

Solution 1

Run the following command: sudo dpkg -P virtualbox-3.1 and see if it might help.

The problem may be occurring because you have got residual configurations for the old version on your system.

When typing the above command, make sure that you do NOT change the commands or you may end up break your operating system. Linux OS is very case sensitive; you make sure you stay accurate. I will prefer if you just copy and paste the command in the command prompt.

Solution 2

• On your computer, go on System and then choose Administration.
• Next select the Synaptic (Packet Management), and then choose the package virtualbox.
• Make sure that the Virtualbox you choose is not virtualbox-ose for it seems you use version from VirtualBox.
• After that uninstall.
• Next thing will be either to reinstall VirtualBox 3.1, or you can go ahead and install VirtualBox 4

Regards,

Carl

Have you tried to uninstall and reinstall it back?

Another workaround is to download the latest version of .NET Framework and see if it will work.

It seems that there is something missing in your computer that requires Virtual Box to run correctly so I would really suggest downloading the correct version of Virtual Box and then install it again.

Also, does your UAC disabled?

Your Virtual Box may be is trying to register a COM object with your operating system without administrative privileges.

Try running it as the administrator and enable your UAC.
