Installation path is the path where HC program files are located. This path is given at the time of installation ( Installation step IV ). If you have moved program files for some reason, HC provides an option to change this path.
To change or set installation path:
In Start menu Programs folder, go to NT Web Hosting Controller and click Settings. The Settings utility dialog will appear.
In Settings dialog click on General tab and enter the installation path in Hosting Controller Installation Path box.
