I have a new Lenovo/I7 Intel Computer with 12 GBytes memory and have not installed BB on it as of yet. I own previous versions 6 to 2012, the last two versions on hard drive also, The 2012 edition was a Christmas gift from my daughter. Can I just install it directly to my HD or do I need to install previous versions first to achieve the 2012 installation? By the way, they are all up-grades, except version 6.
