trouble installing 4.5.1 update

I’ve been trying to install this update without success.
I downloaded it a few times to make sure it wasn’t corrupt and each time I click on it, it updates e-licenser than when it goes to the H4 update it asks for the cd- no problem. then it says that it can’t find the haion 1.0.2 update.msp file…?

What to do?
