I managed to get DW8 working as well, apparently without any bugs. Not with the installer mind you, that still crashed horribly.
Like some other users, I have a licensed version that I installed on my old WinXP partition (I'll never delete that archive of files now!). I copied over the Program Files (x86)/Macromedia/ folder into my win2000 bottle, but kept seeing that window that my installation wasn't finished.
I downloaded the FFF crack (which wine reported as being infected with a virus, glad I'm on Linux!), and applied Crack.exe inside the Dreamweaver folder. Voila! I'm now using DW8 on my websites, downloading/publishing files, using templates, etc.
Thank you everyone, this was my final hurdle in switching to Linux, with the exception of half life. ;)
