Actions taken by the install program:

Copies files from the source directory to the directory you chose.

The installer program does not modify the config.sys, autoexec.bat, or
system.ini files. It does add two file associations to the win.ini file
so that you can open People Manager and Info Manager files from the
File Manager.

To manually install Opportunity for Windows, simply copy all the files
from the source directory to the directory of your choice. You can also
associate People Manager and Info Manager files from the File Manager.

Most users will want to use the Installer program though. Just run the
Install program to install Opportunity for Windows on to your System.
