The article addresses a login problem to the SA client on Windows 7


When attempting to start the Server Automation (SA) client on some Windows 7 workstations, as soon as the Login button is pressed, the client windows freezes and becomes grayed out. The client never connects to the SA core. This may occur the any time the client is started, though most frequently it will occur when a new client is installed and run the first time. A stack trace similar to the following will also be present in the error.log file in the SA client folder on the workstation

This failure is caused by the locale setting in the SA Client being set or reset to a null value.


To workaround the problem, set a valid locale for the SA Client.

  • Start the client
  • Set values as needed and appropriate
  • Click on the Advanced button
  • Click on the resulting More button
  • Set the locale field to a valid value for your workstation; typically, this will be one of <en>, <ja>, or <ko>
  • Login to the SA core
