The link to the configurator points to a non-existent file.  Turns out there is a file in the directory but with a different name - A3XX in the filename instead of A318_19.  The rest of the filename looks ok.  Also the "Start In" entry in the shortcut  begins and ends with double quotes = "" instead of ".  With these changes the configurator appears to work.  Have I broken something by changing the shortcut in this way?  (I am running p3dV4.3 on Windows 10 if it matters.)
