         <source>Failed to load %1. Your Cppcheck installation is broken. You can use --data-dir=&lt;directory&gt; at the command line to specify where this file is located. Please note that --data-dir is supposed to be used by installation scripts and therefore the GUI does not start when it is used, all that happens is that the setting is configured.
