Everytime I try to start MATLAB I get an error message (picture attached). Can anyone tell me what I should do different? Thank you so much!

That's a strange error. Did your MATLAB installation install successfully and completely? Is your Java installation up-to-date? Try installing the latest Java version, get it here: http://java.com/download.

MATLAB: Does MATLAB crash at startup with the error “Cannot locate com/mathworks/jmi/OpaqueJavaInterface class”

This error may occur if you have set a MATLAB_JAVA environment variable for a previous version of MATLAB. If this variable is set, you will need to unset it in order to run MATLAB. For more information on MATLAB_JAVA, see one of the following articles:

How do I change the Java Virtual Machine (JVM) that MATLAB is using on Windows?
How do I change the Java Virtual Machine (JVM) that MATLAB is using on macOS?
How do I change the Java Virtual machine (JVM) that MATLAB is using on Linux?

This error can also be caused by a java.opts file on the MATLAB path. If you are using Windows and you have checked your path for java.opts files, but you are still receiving this error, make sure the "Start in" field in your shortcut is set to a directory that doesn't contain a java.opts file.

If MATLAB_JAVA is not set and java.opts is not present, then your MATLAB installation may be corrupt. Uninstall and reinstall MATLAB to repair your MATLAB installation.

MATLAB: Does the MATLAB 7.11 (R2010b) installer crash saying “Exception in thread “main” java.lang.UnsupportedClassVersionError: Bad version number in .class file”

MATLAB 7.11 (R2010b) requires java 1.6 to run on Mac OS X. This error will occur if you do not have java 1.6 or higher currently installed on your Mac.

To make sure you are most current with Mac Software Updates, go to your Apple Icon in the top left side of your screen and of to "Software Update".

To check to see what version of java you currently have installed, open X11 from Applications/Utilities/. In the command window, type:

java -version

This will tell you what version of Java is currently installed.
