Install Incomplete Storyline 3

i try installing storyline 3 in my win 7 32 bit many times and it tells me that the installation are completely successful but when I opened Storyline 3 app and i had a message error saying that my installation is uncompleted. So I click on the link provided by that message error and it brings me to a 404 web page.
