In LR to get new profiles to show up you need to go to the Print module, click on the profiles dropdown, at the bottom of the list click on "Other", a list of your installed profiles will appear, and you then check in the box to the left of each profile you want to retain in the LR profiles menu. You will need to likewise in the Develop Module for profiles you want for softproofing. Exit the application, relaunch it, and you will find them there. Or you may find them without relaunching, depends.
