Reinstalling and uninstalling Adobe Dreamweaver in a multiuser environment
After you install Adobe Dreamweaver, if you later reinstall it or upgrade to a later version, Adobe Dreamweaver automatically makes backup copies of existing user configuration files, so that if you've customized those files, you can still access the changes you made. When you uninstall Adobe Dreamweaver from a multiuser system (which you can do only if you have administrative privileges), Adobe Dreamweaver can remove each user Configuration folder for you.
