After download the DLS-5Bxx Files have to be unzipped and both Disks should be in the Same folder. Disk one will have setup.exe and after disk 1 is loaded the setup will look for disk 2. Both unzipped Disks need to keep the same naming ie. Disk1 and Disk2. To start the install double click on the setup.exe in the Disk1 folder. Be patient as some of the noise files will take a wile to install.
