Welcome to Linuxquestions.org
When you post at least give info on what distro you are using, Debian, Ubuntu, Red Hat ext.
To install a package/program using dpkg open a terminal window and change directory into the directory you downloaded the package/program to. If you are running Debian su to root give root passwd then type the command dpkg -i filename if on the other hand you are using one of the Ubuntu flavors of linux prefix the command with sudo like so sudo dpkg -i filename and then you will be prompt for your passwd.
To learn more about dpkg, look at the man page, in a terminal type man dpkg
