[2023] Your computer does not have a supported processor (SSE3 support required)

In next hotfix we will change the dialog box to be more accurate.  The real requirement is SSE 4.2 instructions, as per the info provided in the update notes and as warned last year in our system requirements PSA. Sadly SSE4A is not the same thing as SSE4.2,  and your CPU no longer meets the minimum required system.  The oldest AMD CPUs that support SSE4.2 are the "Bulldozer" architecture, which includes chips in the FX-4000, 6000, and 8000 series.
