Error opening the "Open error report" in Matlab coder

Hi there, I'm working on Matlab coder and when I compile a project after I can't open the error report. When I click on the link "Open error report" in the Command window appears "Undefined function or variable 'mat2C'", where mat2C is the name of the folder where is contained the mfile and the project.

thanks a lot for the answer,

Flavio
