I don't know if CC uses startup scripts but I fixed a similar problem running DW5 under Windows XP. I had persistent crashes. Deleting the cache didn't work. If I renamed (or deleted) DW5's preferences, DW5 would recreate its preferences and then crash without ever showing any interface.
My fix was to rename (or delete) the startup script files at C:\Program Files\Common Files\Adobe\Startup Scripts CS5\Dreamweaver\dreamweaver-11.0\ No problems since.
