CS3 Trial Download for Mac OSX

Curious on the left column of Installation window has a check next to each of
the 5 elements then 'Done'
In the main part of window the following is reported BUT without other
explanation I am going to uninstall and try redoing. Advice for a successful
download would be really appreciated. Yes I closed down all other appls before
starting.
Thanks
