Hi all, I was/am getting some errors when matlab starts. I tried to resolve this by uninstalling Matlab, and installing it from scratch. I unistalled all Java platforms, and installed them again. I have also installed the SDK compiler suggested by Matlab. (This fixed simulink issues which was not working at all..now it does.)
However, it did not solve the Java errors... I would really appreciate your help, if you had any similar issue. I am attaching the errors below:
Best regards, M
SOLUTION (as suggested by matlab support) : Install Matlab and Simulink report generators

Try to use matlab in basic (32bit)/Classic theme, if you are using a windows 7 os (Go to desktop right click->personalize->theme -> windows classic-Apply). Good Luck

Same problem for me with 2013b and windows 7 enterprise (sp1). Changing the theme didn't help though. This is a brand new system and brand new installation.
