Windows 7 Adobe Error 1603: Fatal Error During Installation

[SwalloweD]

Alright, so I recently got Photoshop CS4 using Windows Vista,but i just want to try the Windows & Ultimate so i format may laptop change my OS to Windows 7, , . Not sure why, but I got the screen to accept or decline the user end license agreement, when I clicked to accept it, it just went away and nothing happened. So I uninstalled it, and tried reinstalling it, now every time I try, it gets right to the end, where it's installing Adobe Bridge CS4 and it comes up with an error saying it had problems installing photoshop CS4 and then asks me if I want to continue with the installation, I click continue, and it finishes, but I get an error message at the end again. When I click more information I get this:

Adobe Photoshop CS4
Error:
Error 1603. Fatal error during installation.

Adobe Bridge CS4

I'm not sure why I'm getting this error, ​

It may be Windows 7 paranoia, the OS protects the Program Files folder fiercely. The easiest way would be to try to install in C:\ directly. Or in any other place than Program Files.
