How to Install From an ISO Image

By Jason Candanedo

An ISO file is an exact duplicate, or image, of the contents of a CD/ROM. It is like having the original CD without the hard copy itself. An ISO file can be an image of a computer program. By itself, an ISO file is pretty useless. The only way to utilize and install from an ISO image file is to use a number of “virtual software” programs available, such as PowerISO. PowerISO is a virtual CD/DVD drive program, meaning that is plays the ISO files as if a regular CD was in your computer CD/DVD drive. With a virtual program, you can play and install whatever program is in the virtual drive to your computer. For this method, PowerISO will be used.
