As far as I know the current version of PhotoShop CC is only available through their monthly subscription service....$28.59/ month

Any download versions should be treated with suspicion...there are no freebies!
I recommend the latest version of PaintShopPro, free trial available and only costs an once off fee from $45 and does 99% (if not more!) of what PS does...well worth looking at.
