When installing javafx runtime via DT, there is an incorrect message displayed at the end of successful installation

javafx installed OK but this strange message led users toward a negative result, impression - totally confused

*** Tested OS:
- x86 XP(sp2), x86 Win 7
- jre: 7-fcs, 6u27 (dt-awareness)
- DT FX: presidio-deploy-scrum (latest b313)
http://jfx.us.oracle.com/hudson/view/Presidio/job/presidio-deploy-scrum/313/label=windows-i586-14/
- Browser: FF, IE

*** Steps to reproduce:
0) Install jre7-fcs
1) Make sure the system does not have any fx runtime installed
2) Use FF or IE to invoke the page

3) Try to launch this app via java webstart by click 'click to launch this app as webstart'
4) DT kicked in- Follow the flow to install javafx
5) At the very end of completed javafx installation screen, click 'close' the setup dialog

If you see the 'Installation of javafx failed [error:generic]' as attached screenshot, then the issue is reproducible
(in fact, javafx installed fine as the app will load if you either reload the page or close the browser and re-launched again)

The failure message is misled and incorrect. Isn't the message intend to ask users to close the browser instead?
