This configuration variable applies only to the thin client automatic update feature. If this process fails, a message appears informing the user of the failure. In some cases, you may not want the thin client to inform the user that the automatic update failed. If you don't want this message to appear, set the TC_AUTO_UPDATE_NOTIFY_FAIL configuration variable to "false" (0, off, no). The default value of this variable is "true" (1, on, yes).
Note that the message box does not appear if the user cancels the Windows installer download process.
See Automatic Update Failure for more information about this variable.
