how can I tell what Acrobat version

My computer has died and now I need to buy another one used. I'm looking for a macbook pro with the Acrobat X already installed. My question is how can I check to see what version is installed. I don't want to accidentally buy a computer with Acrobat X Standard, I need to have all the features of the Pro version. Where can I look to find out? Some of the guys I've been calling really don't have a clue when I ask them. So can someone guide me so I don't throw my hard earned cutting lawns money away?
