Installation Guide for Windows

Step 1: Before You Install

Before you run the installation program:

Have your Personal License Password (PLP) and your License File handy. A PLP identifies the products that you are licensed to install; a License File identifies the products you can run. The licensing information you receive varies depending on the type of license option you choose.

A PLP is a series of five-digit numbers prefixed with a two-digit release code, such as 14-12345-12345-12345-12345-12345. Depending on your license option, you might receive a PLP for stand-alone installations as well as a PLP for network installations.

A License File is a specially formatted text file that contains an INCREMENT line for each licensed product. See Licensing Components for an example.

If you don't have your licensing information, see Obtaining Your Licenses.

Exit any existing copies of MATLAB you may have running.
Shut down the FLEXlm license manager, if it is running. (See Starting and Stopping the License Manager for instructions.)
Make sure your system satisfies the requirements of the software you intend to install. For more information, see System Requirements.
Get administrator privileges for the system on which you plan to install MATLAB.

In addition, consider disabling virus checking on your system for the duration of the installation process. Virus checkers can slow down the installation process.

Upgrade Installations

If you are upgrading your MATLAB installation to the latest release, The MathWorks recommends that you install the new version in a new installation folder. You do not need to delete an existing MATLAB installation before installing Release 14, Service Pack 3. You can run multiple versions of MATLAB on the same system -- see Running Multiple Versions of MATLAB. For information about adding an additional toolbox to an existing MATLAB installation, see Installing Additional Products.

Note If you choose to overwrite an existing Release 14 installation with Release 14 Service Pack 3, the installer deletes all the products currently in your Release 14 installation folder and installs only those products included in your Release 14 Service Pack 3 license. For example, if your Release 14 installation includes ten products but your Service Pack 3 PLP only includes five of those products, after installing Service Pack 3, your installation will only include the five products included in your Service Pack 3 PLP.

MATLAB Preferences

The installer does not overwrite existing MATLAB preference files on your system. Multiple MATLAB installations on the same system use the same preference files.

Note, however, that if you plan to remove a Release 12 or earlier installation, you might want to first save your MATLAB preference files. Before Release 12.1, the uninstaller provided with MATLAB automatically deleted MATLAB preferences files. See Using the Uninstaller for more information.
