Have you set your PATH environment variable to the bin directory of your quartus? Try this and then re-run 

 Considering you're using Linux: export PATH=$PATH:<installed_quartus_directory>/<version>/quartus/bin

thank for reply, I am using windows, so "export PATH=$PATH:<installed_quartus_directory>/<version>/quartus/bin" command should be taip at where?

Try this steps for windows 

 1) Open up your command prompt (cmd) 2) Type set PATH=%PATH%;C:\altera\12.1\quartus\bin  Change the back party of the PATH after ';' according to your quartus installation directory  Then try to run quartus_sh again

Thank, I can set the path, but i don't know how to remove the 32bits path. However, i exchange the name of bin64 with bin and it is work. It run version 64bits in command prompt.

There is actually another way to set or remove certain paths from your environment variable. In windows, 

 1) Open Control Panel --> Systems --> Advanced system settings --> 'Advanced' Tab --> Environment variables 2) Look for Path and click 'Edit' 3) Type the path manually and/or remove the ones you don't want

Yes, I am using this way, but is it same as when i type "path" in my command prompt? because when i type path in my command prompt, it show many applicationpath like MATLAB or other, but if i open environment variables, i only can see modelsim and quartus path.
