I want to use GAMS in Fedora (23). I have read the information on how to install GAMS in Unix (https://www.gams.com/help/index.jsp?topic=%2Fgams.doc%2Fuserguides%2Fuserguide%2F_u_g__i_n_s_t_a_l_l.html&cp=0_1).
I have downloaded the file to a folder and successfully ran:
chmod -x linux_x64_64_sfx.exe

This appears to be provided as a self-extracting archive ("sfx" is a typical convention for referring to such archives; "exe" is a DOS/Windows thing, but looks like they just kept that to be consistent and it is a Linux binary).
The messages you are seeing come from that extraction. The fact that it says you are overwriting files in a
gams24.7_linux_x64_64_sfx/ subdirectory strongly suggests that you already ran it, and are now doing the same thing again. It's telling you that the files are already there, and I bet if you do
ls gams24.7_linux_x64_64_sfx/, you will see them.
The instructions you linked give
- Change to the GAMS system directory and run the program
... have you tried that?
