Aptana Studio Professional 1 5 1 doesn’t install correctly.

Hallo there!
I have Aptana Studio professional 1 51 but it has refused to install. I do not get any information on why it cannot install, only that I click on the setup and nothing happens. I thought that it could be that the Compact Disk I was installing from is corrupted so I got a better and working setup but I am still having the same problem. What can I do to have it installed correctly? Thanks.
