[TRNSYS-users] Exporting file

Hi everybody,
Can anyone tell me, how to activate 'Export as....' option from the File 
menu? I have followed the steps in section 1.9 of TRNSYS 16- Getting 
Started. However did not manage to export the file after saving in TRASYS 
16\Studio\Proformas\My components... Whether this could be because of no 
FORTRAN/C++ is loaded in the PC?

Thanks.
Papia
