Photoshop is not working on my older PC I have read countless and countless of complaints about why Photoshop will not work with older systems anymore, and the answers are clear: they do not meet the requirements for a CPU that supports SSE 4.2 or later. Be that as it may, but I want a straight answer from Adobe telling why most of the other CC apps work, such as Premiere Pro which is by far a more resource-hungry and heavier program than Photoshop. What makes Photoshop so picky about some "SSE"? Photoshop is one of the key applications in the Creative Cloud family, so it feels, IMHO, that Adobe is deliberately trying to piss people off with this. Moreover, the older Photoshop versions that are still available, seemingly compatible, don't work anymore, either. Paying (yes, that's right, it's our money) customers should be able to go back as far as possible to find a version that still works, or our money back.
