The full administrator account has merit, if you haven't already tried it.
Besides helping me run my custom computer business, my wife is IT for an aged care facility chain. First thing she did was try that logging on with the full adminstrator account and taking ownership, but didn't solve her problem. She also tried to take ownership manually. (She tends to feel insulted when suggesting scripts to her as I think she's still secretly in love with DOS, but I prefer anything that makes my life easier.)
As I said, there's 2 different things going on here with ownership. The first problem is folders/files that were created before an upgrade, or from another OS on a dual boot system. For those taking ownership usually works fine with the provided user/administrator accounts (have to turn on administrator as MS for whatever reason decided to leave it off by default). The full administrator usually works when that doesn't.
The second problem is corrupted data by Win 7 on random folders/files that were created on Win 7 with both user and administrator accounts. No fix that I've seen to date solves that, and its happening more often than people may realize. We even tried attaching the hard drive to another system as a data drive and logging in as full administrator. The files read fine, but can't be edited, moved, nor removed.
The only other thing I can offer Filmguy is to try and install over the top as full Administrator to add the missing files (uninstall). If it works, then you may be able to uninstall and start over (I've seen that before too occasionally). We have CS4 installed correctly on a couple systems with Win 7 64 bit. I don't know of an Adobe program that is not (supposedly) supported with Win 7 yet, but I could be wrong. Hope you get it sorted out. :)
