I bought this back in Feb. and installed it on my laptop and home desktop. I was going to sell it on ebay, but I'm not sure how easy it is to transfer the license. It comes with two serial #'s, which I activated on each computer. It says you can deactivate and reactivate each license 5 times per calendar year, so I assume you could install it on another machine without any problems. If somebody is interested in giving it a shot, make me an offer, otherwise I guess its garbage since I no longer have my A4. Wouldn't have been a problem if they just made a paper copy!!!
