I don't know what that was about, possibly a hang over from previous attempts.

When you say it "got closed" do you mean you closed it or it did it

It should be installed.  Is flash working?

If, in a terminal you do
apt-cache policy flashplugin-installer
what do you see, and in Firefox if you go to Tools > Addons > Plugins
you should see Shockwave Flash.  Which version does it say it is?
