This configuration variable applies only to the ACUCOBOL-GT Thin Client automatic update feature. The thin client uses the value of the TC_INSTALLER_ARGS configuration variable as the command-line options passed to the installer executable. For example, if you want msiexec.exe to log all of its operations to a file named msi.log, then you could set TC_INSTALLER_ARGS to /log msi.log. TC_INSTALLER_ARGS has no default value.
See Thin Client Automatic Update in the AcuConnect User's Guide for detailed information about the thin client automatic update process.
