Where are vst files

Thanks for your help. I got it in the end and I think I am a dummy and missed a very crucial detail. Remember I'm new…In case your interested I was making the mistake of thinking the instrument was the vst and not kontakt. You all helped with that. So I have a "wrapper"? that I found that allows mpc beats to see vst3 files, that worked with some noise engineering downloads. But here i was dumping the sound library into the wrapper instead of kontakt itself….I think. But what I was maybe missing and makes me a huge doofus is that I did not open the window for kontakt in mpc, I thought the instrument would show up in the lower bar and I just need kontakt open on my computer. That midi number is waiting for me to make a preset and assign it to it

. So the crucial detail is not pressing that stupid little box with an arrow saying "LOOK AT MEEEE" and i didn't…….
