I cannot get Virtualbox to install properly on my 12.04. I first went with a manual install for the .deb from the old builds section of the Virtualbox page. That .deb opened up the Software Center and installed. Then I got the error coming up of

VT-x/AMD-V hardware acceleration is not available on your system. Your 64-bit guest will fail to detect a 64-bit CPU and will not be able to boot.

which I can only assume was due to my Ubuntu version being 32-bit (System Details -> Overview -> OC type: 32-bit, right?)
So I followed these instructions to remove the .deb manually, restarted my laptop, and then FOUND the actual Virtualbox install in the Software Center and installed from that (assuming it would give me the correct version I need for my system)

So after all that (and then some), I'm still getting the same error when I connect to my new job's project in Virtualbox.

Can anyone point me in the right direction of what to do here? This is the first time I've ever worked with Virtualbox, and no one at this company is using Ubuntu, so I'm on my own here.

EDIT: Here is the direct info from running the 2 suggested commands
