Welcome to the wonderful world of Adobe software... Run the Creative Suite Cleaner Tool, reinstall your trial, then attempt to apply the patch. Could be, though, that it only works on serialized installs, so it may never actually install on your system. Stranger things have happened...
Well I tried. Did everything suggested and I'm back tyo where I started.
In case it helps, I'm on a Macbook Pro Retina display. 8 gig ram etc.
