frankly, i am really getting tired of the SW installation manager. it is a PITA and a completely unecessary piece of overhead. definition of the word "clouge"

nevertheless we are stuck with it and now when i try to install, i cannot select the "download and install" button cuz it is greyed out. in fact i do not want to download at all as i already have downloaded all the files. i cannot figure out why as i have made all the necessary file location changes. i am installing from a networked computer. could it be that  i do not have a free license?
