Standard Installation Procedure (MATLAB Installation Guide for Windows) MATLAB Installation Guide for Windows     Installing Additional Products   When you order additional products, The MathWorks sends you a new Personal License Password (PLP). Your PLP identifies all the products you are licensed to install. To install additional products: Shut down MATLAB. Insert the product CD into your CD-ROM drive, or double-click on the file you downloaded from the MathWorks Web site. The installer starts automatically. Follow the instructions on the installer dialog boxes, detailed in Standard Installation Procedure for Windows Systems. (For network installations, follow the instructions in Network Installation Procedure.) When you select the products to install in the Product List dialog box, described in Step 5: Select the Products You Want to Install, note the following: Specify your current MATLAB installation directory as the installation directory. Select only the new products for installation. By default, the installer lists all the products you are licensed to install and preselects them for installation. To only install the new products, click in the checkboxes next to the names of the products that you do not want to install to clear their selection. When the installation program is finished, perform any configuration required by the new products. See Configuring Certain Products for more information. Upgrading a Demo License Installation To upgrade a demo license to a standard license, without having to reinstall any products or documentation, follow this procedure: Get your new PLP. Run the installation procedure, described in Installation Instructions. At Step 5: Select the Products You Want to Install, click the More Options... button on the Product List dialog box. In the dialog box displayed, select the Update license without installing anything option. Click Next and complete the installation. You can use this option to Extend the expiration date of a demo license. Convert a demo license to a standard license, without reinstalling MATLAB. Move your installation onto a new system. When you choose the Update license option, no products or documentation are installed. The installer disables items 2 and 3 in the Product List dialog box.   Finding Information About MATLAB Removing (Uninstalling) a MATLAB Installation
