Adobe CS4 Master & Windows 7

I read another thread about issues but it was different and quite old so forgive me if it is wrong of me to post my own thread due to different issues.

I have a good PC (not top of the line but good) and just installed Windows 7 Ultimate 32 bit and want to install Adobe CS4 Master on it but keep running across an error when I try.

I meet (and exceed) all system requirements and actually ran CS4 on my pc when I was using Vista Home Edition 32 bit so not sure what to do now...

It initially runs through the system scan and goes great, that error comes up at the very next window.

I have run it through compatibility mode for both Vista and XP with the same issue... this is getting insane !!!

Any help would be GREATLY appreciated
