Problems with File Permissions

The installer must have write access to the installation directory. If the installer cannot write to the installation directory, it displays an error message.

To continue with the installation, dismiss the error message dialog box and use the chmod command at the UNIX prompt to change the permission setting of the installation directory. Your file mode creation mask (also known as your user mask) controls the default permissions assigned to new files and directories. You can use the umask command to change this default.

The suggested file permissions are read, write, and execute permission for the user, and read and execute permission for the group and the world (other), represented in a UNIX directory listing as

drwxr-xr-x

The following example uses chmod to set these permissions on a directory.

chmod 755 matlab

To provide complete access to users, group, and the world, specify the value 777.

Problems Opening the Display

If, after starting OpenWindows or Motif, the installation program outputs the Can't open display error message, enter the following command at the UNIX prompt:

xhost +x

Then restart the installer.

Problems with a Host ID Mismatch

If the host ID in the comment line of your License File does not match the host ID of the system on which you are performing the installation, the installer displays the following error message on your screen:

Host ID in License File Doesn't Match Host ID of System

This typically indicates that you are using the wrong License File for this system. You can continue with the installation, but you will not be able to start the MATLAB program.

Problems with Your DVD Drive

To diagnose a problem with a DVD drive:

• Verify that the device is mounted correctly.

• Verify that the DVD device file has the correct read and execute permissions. For example, on Linux systems, DVD drives have read-only permission by default. To check a device's permissions, use the UNIX command:

  ls -l device
  

  where device is the device name for your DVD drive. To change permissions, log in as superuser and run the UNIX command:

  chmod 555 device

Accessing Activation Options

Specifying Proxy Server Connection Settings

If your Internet connection requires a proxy server, click the Advanced Options button on the first dialog box of the activation application. You can enter the server name, port, and password in the Advanced Options dialog box. The MathWorks supports several types of proxy configurations: Basic authentication, Digest authentication, and NTLM authentication.

Activating Without a MathWorks Account

While every user can benefit from having a MathWorks Account, it is possible to install and run MathWorks software without one. For example, at some sites, some users may not be able to create an account for security reasons.

To activate without providing MathWorks Account information, follow this procedure.

1. Start the installer. On the first dialog box, select the install manually without using the Internet option. You will need a File Installation Key. (See Installing and Activating Without an Internet Connection for complete instructions.)

2. When the installer finishes installation and displays the Installation Complete dialog box, leave the Activate MATLAB option selected and click Next.

3. On the first dialog box displayed by the activation application:

   • Choose Activate automatically using the Internet. To install and activate without associating with a MathWorks Account, you must use the Internet.

   • Click Advanced Options. In the Advanced Options dialog box, select the Activate without associating to a license option and click OK.

     

   • When you return to the first activation dialog box, click Next.

4. Enter an Activation Key in the Activation Key dialog box and click Next. Because you are not logged into a MathWorks Account, you must enter an Activation Key to identify a license.

   Note   The only activation type available for unassociated activation is Designated Computer.

5. Click Activate.
