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 code, such as 16-12345-12345-12345-12345-12345. 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.
Consider disabling virus checking software and internet security applications on your system for the duration of the installation process. These applications can slow down or hang the installation process.

64-Bit Availability

The MathWorks offers both 32-bit and 64-bit versions of MATLAB. To determine whether your system is a 32-bit or 64-bit system, right-click on the My Computer icon on your desktop, select Properties, and look at the System information on the General tab. To download the 64-bit version of MATLAB, go to the downloads section of the MathWorks Web site, www.mathworks.com/web_downloads.

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 this release. 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 installation from a prior release, the installer deletes all the products in your installation folder and installs only those products included in your current license, to avoid potential product incompatibilities. For example, if your existing installation includes 10 products, but your current PLP only includes 9 of those products, your MATLAB installation will only include the 9 products included in your current PLP.

Saving MATLAB Preferences Files

The installer does not overwrite existing MATLAB preference files on your system. 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.
