how can i solve this installation problem with matlab r2014a (32bit and 64 bit on windows 7)

hello, I' am getting some errors when matlab starts (new installation r2014a 32bit, also tried with 64 bit, same errors)Prob. Java related.

Hi,

1. As specified in the system requirements link below, the Simulink Report Generator requires MATLAB Report Generator and Simulink. http://www.mathworks.com/products/availability/#SR
2. “rptgenslxmlcomp.jar” is part of Simulink Report Generator and depends on “rptgenxmlcomp.jar” which is part of MATLAB Report Generator. The error seems to indicate that it may be “rptgenxmlcomp.jar” or “rptgenslxmlcomp.jar“ that are missing.
3. Please check if the files “rptgenslxmlcomp.jar” and “rptgenxmlcomp.jar” exist at the path that you get after executing following MATLAB command.

    >> cd([matlabroot,'/Java/jar/toolbox'])

4. Both the MATLAB Report Generator and Simulink Report Generator need to be installed along with MATLAB and Simulink.

Ok thank you. I solved unistalling Simulink Report Generator toolbox.

I have the same or similar problem. The file rptgenslxmlcomp.jar is present in the path.

Please check point 2.) of my post.

rptgenslxmlcomp.jar” is part of Simulink Report Generator and depends on “rptgenxmlcomp.jar” which is part of MATLAB Report Generator. The error seems to indicate that it may be “ rptgenxmlcomp.jar ” or “ rptgenslxmlcomp.jar “ that are missing.
