Aside from what @davescm already stated: Are you even sure this obsolete version would work with the OS on your new computer?
To me it seems some people who decide to stick with obsolete software because they don’t see a benefit in the newer fearures forget that compatibility with newer OS’ and hardware are »features«, too. (edited)
Just so you know, you can get the latest version of Photoshop and updates as they become available plus Lightroom and some storage for about $10 a month. Why not download the seven-day free trial to see it on your brand new computer; there's lots of new features, and it will be compatible with your system.
