Adobe CS3 Windows 7 installation says does not meet minimum requirements

Question

I am trying to install Adobe Creative Suite 3 Design Premium on a brand new Windows 7 machine (32-bit). It is a downloaded copy from Adobe's website.
When I start the install process, it takes me to the "Options" Screen and will not let me install Photoshop, Illustrator, or InDesign. All those options are grayed out.
At the bottom, the reason it gives is as follows:
"The minimum system requirements listed below needed to run adobe photoshop cs3 are required and are not met:
- Windows XP (Service Pack 2)
- Windows Vista"
It gives the same error for the other 2 programs as well.
I have tried the following troubleshooting steps already with no luck:
1. Run Setup.exe as Administrator
2. Run Setup.exe in compatibility mode (either as Windows XP SP2, or Windows Vista)
3. Logged-in to Administrator profile and tried installing from there
4. did the regsvr32 on both vbscript.dll and jscript.dll.
5. Tried the CS3 cleanup tool at multiple levels.
6. Made sure there are no other Adobe products installed
7. Called Adobe Tech support, they are no help. They said to re-install the OS, which doesn't make any sense since it's a clean install.
No AV installed yet, so that's not the issue either.
Any ideas?

I realise I'm a bit late to the party here.. but after spending a few hours going through the Adobe CS3 Bootstrapper and Install process and files, I have the answer to why Windows 7 does not meet the minimum requirements.
The answer is in the xml files contained in the payloads for the CS3 Installation.
Line 72786 of AdobeIllustrator13en_US.proxy.xml :
<SystemRequirementsJSON>[
     {"OS":{"Windows":{"XP":{"Exclude":true,"Require":{"MinServicePack":"2","@servicePack64Bit" :1
,"Need64Bit":"0"}},"Server2003":{"Exclude":true},"Vista":{"Require":true}}},
                              "Memory":{"System":{"Default":{"Require":"512","Exclude":"500"}}},
                              "Display":{"Default":{"Require":{"Width":"1024","Height":"768"},"Exclude":{"Width":"800"," Height":"600"}}}
]</SystemRequirementsJSON>
Basically it is this: For Adobe Illustrator CS3 the following is supported: Windows XP SP2, or Vista ONLY
Not Windows XP SP2 or above, or Windows XP SP2 and Vista or above ...
The same is in several other files, but not all. Illustrator and InDesign are the 2 that I know of.
I have 500 odd machines that I need to deploy this software to.
If Adobe would like to offer a work around with consideration to deploying the software silently via Microsoft SMS to 500 Windows 7 Workstations - I would be most grateful.
My rage at software installer developers with such little foresight is only tempered by the knowledge that the task itself is so difficult.
However, that does not excuse the lack of thought given to how enterprise level administrators are supposed to deal with updates, patches, and deployments to machines where users have limited rights, and the difficulty that is caused by the inclusion of unhelpful and sparse documentation and software (such as Adobe Updater).
