In the DXF-DWG translator setup dialogue, when you select a translator you will see its location.
As far as I know it could be in a shared network location, but I have mine in my office library.
Once you know the location you can send that file to your colleague and they can place it somewher they can access it.
They will need to use the 'Browse' button to add that translator to their list.
I am not sure if you place the XML file in the default user file location (see the default translators 01..., 02..., 03... 04... for location), whether they will load automatically when you next start Archicad, or whether you still need to browse for the file to ad it to the list.
