This is a software program that installs applications and other software onto your computer system. A typical application program may require many specific supporting system files before it can run properly. Programmers use the installer software to package all these files together. Depending on the size of the application, this could be a single file containing all the required data to complete the installation of the application software. The primary goal of installer programs is to hide the complexity of the installation process and to reduce the entire process to a point and click operation that can be used by any person whose knowledge of computer systems is minimal.
