How to Install Dialog

Often, people come to us complaining that our installer is giving errors and fails to run. The basic reason could be unavailability of the "dialog" package. Our installer uses this package to display the GUI inside your server. Installing dialog on a CentOs, Fedora or any RedHat Flavor of linux is very simple.
Just do the following :
yum -y install dialog
Once this is complete, dialog should be installed and you should be ready to go.
