I like this a lot.  It's *much* better than my approach.

My only suggestion is that you rethink what the confirm page should do 
in "download only" mode.  Maybe that page could even be skipped.  But if 
you think the user should confirm the download, there's no need to 
mention "uninstall" actions, and "install" actions should be reported as 
"download".
