Can't Uninstall Dreamweaver!

Question

This is ridiculous. After having issues getting setup.exe to
start (had to set explorer as my default browser for it to work;
don't ask me why), I now have a problem where I can't re-install
dreamweaver as it thinks dreamweaver is already installed. I've
removed absolutely all application files (including those in
Documents & Settings, and those scattered amongst the program
files folder including associations in the 'Common' folder)
including performing a full system search for files & folders
including the word dreamweaver, additionally, I've used regseeker
to scan the registry for all keys including the word, or somehow
associated with the word dreamweaver (over 1000 registry keys
gone).
All that and I still can't install Dreamweaver CS3. Here's a
screenshot of what I'm getting as my error...

I'm guessing there's probably some kind of hidden DLL in the
windows directory which although doesn't contain the word
dreamweaver in the name, is probably associated with dreamweaver
and so the setup.exe probably checks for that file.
Would anyone happen to know how I can either satisfy this
setup.exe or some how force it to install?

Answer 1

Now aren't I just fantastic, 99,000 google searches later, I
manage to work it myself without the help of any resource. I
decided to run Filemon which monitors file access by applications.
I started capturing activity after I launched setup.exe and stopped
it once I saw the dreamweaver currently installed error (screenshot
in original post). At first glance I didn't see anything unusual,
but then I noticed that setup.exe had accessed a file named caps.db
quite a lot which was located in C:\Program Files\Common
Files\Adobe\caps\caps.db
I decided to remove the whole folder as caps.db was the only
thing inside the 'caps' folder. I then restarted setup.exe and bam,
no error. I'm currently installing dreamweaver now. If I don't post
back here, it means deleting caps.db hasn't affected any other
adobe applications, otherwise, I'll probably post back and let you
know :)
I hope this helps someone else as after googling, I'd found a
few others experiencing the same thing but with photoshop (it's all
very much the same).
