Install a program from a disk on Ubuntu Linux

How to install a program from a disk on Ubuntu Linux?

If its a program from a cd it may not work. Ill assume that it is windows software. It may work under WINE emulation, workability varies. If downloading from the internet, the installer that Ubuntu used is called a .DEB file. And, if a program doesnt have an ubuntu installer, you can usually compile from its source code (not always easy).

For flash, go to the link below. Download the tarball (.tar.gz file). Extract the contents. open the newly created folder (install_flash_player_9_linux). Double click on flashplayer-installer. When the prompt comes up, "run in terminal". Follow the commands and enjoy.
