The thin client automatic update feature is enabled by default. The feature can be disabled in one of three ways. You can:
               
               
                  
                  - Set the atc-auto-update thin client command-line variable in the .atc (or .acutc) file to "0" (off, false, no). The default value is "1" (on, true, yes). 
                  
- Set the TC_DISABLE_AUTO_UPDATE runtime configuration variable to "1" (on, true, yes). Default value is "0" (off, false, no).
                     
                  
- Use the --noautoupdate command-line option to acuthin.
