If you need to add a control switch to XCode, you'll need to first navigate to the XCode install directory, then open the BIN folder and edit the xsysconfig.xml. Typically this is found here - C:\Program Files\IPV\XCode Service\Bin\xsysconfig.xml

Add an extra param line as follows. What you enter may vary depending on the control switch you are hoping to add. For example, if you wanted to add the ignoreuserdata switch you would put:

<param name="CONTROLSWITCHES">ignoreuserdata</param>
