Installation Guide for Windows

Step 1: Before You Install

Before you run the MathWorks Installer program:

• Have your Personal License Password (PLP) handy.

• A PLP is a series of five-digit numbers prefixed with a two-digit release code, such as 14-12345-12345-12345-12345-12345. Your PLP identifies the products that you are licensed to install. When you purchase products, The MathWorks sends you a PLP by e-mail or fax. If you don't have your PLP, you can get it by clicking the Get my PLP button on the License Information dialog box, or by contacting The MathWorks. See Obtaining Your Licenses for more information.

• Exit any existing copies of MATLAB you have running.
• Make sure your system satisfies the requirements of the software you intend to install. For more information, see System Requirements.
• Get administrator privileges.

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

When upgrading an existing installation, always install MATLAB in a new installation folder. You do not need to delete an existing MATLAB installation before installing Release 14. You can run multiple versions of MATLAB on the same system.

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 automatically deleted MATLAB preferences files. See Using the Uninstaller for more information.
