The links to download the prerequisites for the Turbo products point to Borland servers that no longer work. The prerequisites need to be downloaded directly from Microsoft's web site and then manually installed on the system before the Turbo products can be installed.
Go to http://download.microsoft.com and search on each of the prerequisites listed below. Copy and paste each of the prerequisite names into the download search box. The MDAC 2.7 and IE 6 prerequisites are normally not needed as most new systems have MDAC 2.8 and IE 7 or IE 8 already installed. Follow the installation directions on the Microsoft download pages for each prerequisite.
