Q: … I would like to know if this GAMS build is it self a 64 bits program? Sometimes Windows says it is a 32 bit program…
On the 64 bit GAMS system, some components are still 32 bit applications:
gams.exe
is a 32 bit application; but it calls gamscmex.exe
to do the actual GAMS work which is 64 bit. For more information, which solver are available as 64 bit versions, please check the current supported platforms.
