I am trying to google the answer but coming up with nothing useful...

Is this even possible, in any way? Thanks!

You'll probably have to create a DLL that calls the cpuid instruction, because the IsProcessorFeaturePresent WinAPI function doesn't appear to support anything beyond SSE3.

2024 update: IsProcessorFeaturePresent WinAPI function does AVX(1),AVX2,AVX512F now also.

Where is this functionality in InnoSetup?
