You have two installation options:

     QUICK INSTALL: Quick Install copies all
  program files to a directory named C:\BACKSOON,
    creating this directory if necessary, and
    allows you to print the documentation to a
   printer connected to parallel port 1 (LPT1).

     FULL INSTALL: Full Install allows you to
     specify the drive and directory in which
 you would like to install BACK SOON! Version 2.x
  and to print the documentation to any printer.
