The next few screens allow you to select where and how much to install. Brief descriptions are listed below: The "Typical" option copies all of the major components to your system. This option performs best. The "Compact" option leaves all of the files on the CD. The performance of the program will be slower than the typical option. The "Custom" option allows you to select which major components to install and which to leave on the CD. This may require the CD to be present for some program options to work properly
