Dear Seniors,

Here I just to ask about the GMT version 6.3.  
I just installed it on my windows PC, but when I tried to switch GMT command in CMD there is no list of GMT 6, how can I solve this ? thank you for the cooperation.

Hi Geovanio,

I’m sorry but I fail to understand your question. Are you trying to switch GMT versions (in case you had a previous one installed)? Or are you trying to run a GMT command and it doesn’t work? (Was there a little windows warning that the installer was not able to update the path and the warning was ignored?).
