I'm sorry. The only question that I see is to unpack "install", which I take as a figurative expression meaning to analyze something into its component elements. I broke down everything that I meant to imply by the word, so you'll have to ask a different question.

Edit to reply below: your probability analysis ignores Elop's improbable behavior as described by hollerith above. And, again, this is not my explanation (this conjecture was all over threads discussing the deal the day it was announced). I'm not even saying that I buy into it, although I do have to acknowledge that people involved with deals in the billions of dollars are seldom strangers to opportunism.
