I had the 2013 version which came with 3 licences and had no problems with that so buying the 2014 version was a no brainer. It is VERY easy to install. You need to set up an online account and register each PC or laptop you have installed to get the virus updates. This is simple to do. The 2014 version seems better than the 2013 version as it warns me if I have forgotten to install Windows updates. I have loaded this on a Windows 7 laptop, a Windows 8 PC and a Windows 8 Laptop all are running fine.
By the way if you do buy this DO NOT automatically renew with the company at the end of the year. The price they quote is expensive. Instead buy a 2015 version on Amazon it is MUCH cheaper.
