I recently had to change my computer and when I tried to download After Effects CS3(because I've tried CS4 and i feel more comfortable using CS3) it says my computer needs to be i think SSE2 it said? Can some1 help me out?
I have an AMD Anthlon(tm)XP 3200+ 2.20GHz, 1.93gb of Ram
unfortunatelly - it doesn't support SSE2. SSE2 support begins with AMD Athlon 64
Yupp, SSE2 was introduced around the time the processor was released, but naturally, as an intel technology, it took AMD a while to license it and add it to their chips as well. So this is a no-go. The machine is simply too old.
