Before you can install MATLAB you will need the following.

1. MATLAB ISO/DMG file (As of R2016b the MATLAB installer is split across two ISO files for Windows and Linux)
2. MATLAB license file
3. File Installation Key

Note: Please temporarily disable anti-virus software and Internet security applications on your system for the duration of the installation process. These applications can slow down the installation process or cause it to appear unresponsive or to hang.
