Just want to point out that CS6 is not CC. Creative Cloud has that subscription model, and a number of people don't like that.
This is a main reason why I'm still using Photoshop 7. I've squeezed my money's worth and then some out of PS7, and it still works (rather well actually) on Windows 10. Yeah it's a 32 bit program on a 64 bit system, so I did have to partition one of my drives to make a subdivision of suitably smaller size that was '32 bit' friendly for the scratch disk.
I'm sure I'm missing out on some functionality that has been introduced into later versions, but PS7 does everything I need it to. It'd be cool to have more styles, etc. but there are actually still quite a few resources available online for PS7, even after all thse years.
I'm kinda curious as to how
@Jaguarundi's share will work - i.e. could that work with the same serial # as the 32 bit version... for those that like 'legal' upgrade paths for their CS6 from 32 to 64 bit.
