License file woes related to problem with installer and Java

I need to update the license, but when I launch matlab with the new license file I get error -13, which says to reinstall the license manager.

I determined that I need to run the install file.

Running the install file gets me the following error:

Exception in thread "main" java.lang.NoClassDefFoundError: com/mathworks/professionalinstaller/Launcher Caused by: java.lang.ClassNotFoundException: com.mathworks.professionalinstaller.Launcher at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) Could not find the main class: com/mathworks/professionalinstaller/Launcher. Program will exit. Finished

What went wrong?

Running: ROCKS Linux (based on CEntOS), Matlab 2012a
