Before you can start GeODin Shuttle (via the gshuttle.exe), you must install the software. For this purpose, please download the current GeODin Shuttle setup, unpack the ZIP archive and execute the program file (.exe) contained therein.
You can also use an already existing GeODin installation (e.g. that of your licensed version) for GeODin Shuttle. Usually, the gshuttle.exe is already located in the BIN directory of your GeODin installation and you can simply start it from this directory.
