Some people have successfully installed and run the software on Win7, but considering that it's not an officially released OS, Adobe hasn't officially qualified CS4 for Win7, and it won't be qualified until its released.
Short story: you're on your own.
As long as you install Windows 7RC as an "upgrade" - as opposed to a fresh install - all your existing apps should just be there after the process has finished. So you shouldn't need to re-install anything.
That said... Windows 7RC is still unsupported. There's a possibility that a particular combination of Windows / Hardware / Software could cause a problem.
But it worked just fine for me, on both my main PC and laptop. And I would recommend it but with that note of caution.
Make sure you deactivate CS4 before you shut down to redo your system if you are going to reformat and start all over. Prepare for a 800 MB download to upgrade Production Premium to the latest version.

Thanks everyone, this is the information I needed
There have been some instances, reported on the PE board, where Win7 and PE were working fine. Then, with two recent build releases of Win7, things went south in a hurry, and PE would no longer run at all. As Win7 is still in beta, it is a dynamic thing. Some iterations seem to work fine, and then things change.
Were I doing this, I'd definitely go dual-boot, or dedicate a machine just for testing the OS.
PS to Bill - that is a common occurance with me lately. Sometimes I'm logged in for a few days, and then get kicked out while trying to post, immediately after anothe successful post. Edit is a hit, or miss proposition for me too. Sometimes, I can Edit after 2 days, and sometimes, 45 sec. is too long and no Edit option?!?!? Phases of the Moon?
