Thanks so much for your interest and suggestions. Not sure how to check.
There seem to be 3 folders: PSE8, PSE8All and PSE2-mul.
PSE8 is from the copied CD now on a flash Drive, with seven folders including PSE Setup - from which I'm trying to install.
The other two had 3 folders in each - which I've moved to trash but the folders remain with nothing (in case they were interfering)
There are no downloads.
Now when I Set up, the System Profile is checked, followed by the RIBS installer window with Easy Install recommended and when Install is clicked it starts and then the window disappears.
Further help to a 'silver surfer' - please
