Reverence missing IR's

Hi
I would be nice if someone with knowledge about Reverence would post a detailed instruction how to find it’s IR’s and install them on a mac & win system. I have been all over the net and many people have issues with missing IR’s, but until now there are no solution.
Somebody say that they used C7 installer DVD’s but not which one and how. You can’t run the C7 installer on a mac with 10.10.5!
Any Help Much Appreciated!
