Problems During Installation

This section provides answers to some problems commonly encountered during installation.

Note If the MathWorks Installer appears to hang, you may want to turn off any virus checking software you are running on your system and restart the installer.

The Installer Does Not Start Automatically

The installer should start automatically when you insert the MathWorks CD into your CD-ROM drive or when you double-click on the installer file you downloaded from the MathWorks Web site.

If the installer does not start, open a Windows Explorer window, select your CD-ROM drive, and double-click the setup.exe program in the top-level folder.

Invalid Personal License Password

During installation, you must enter your PLP. If your PLP is invalid, you cannot continue with the installation. Verify that

You entered your PLP in the Personal License Password dialog box. Do not confuse your License Number with your PLP. A PLP is a series of five-digit numbers, prefixed by a two-digit release code, such as:

```
14-12345-12345-12345-12345
```

You have a current PLP. PLPs are version specific. Do not use an old PLP with a new version of MATLAB.

License File Could Not Be Updated

You can receive this error message when you are using the installer to update your licenses -- see Updating a License.

There are two reasons why you received this message:

The license file (license.dat) in the $MATLAB\bin\win32 folder is invalid.
You have multiple valid license files in the specified folder (e.g., demo.lic and license.dat).

For information about troubleshooting License File issues, see Licensing Information.

Failure Overwriting an Existing Toolbox

You can receive this error message when you attempt to perform an installation when an existing MATLAB installation is running. Make sure that you exit from all existing copies of MATLAB before attempting to run the installation procedure.
