Graphical Spring Design Software Version 5 (GSDS5)

The support for this software has been discontinued. If you are getting error messages, you may wish to consider purchasing the latest SMI software, Advanced Spring Design, which is fully compatible with Windows XP and 2000, click here to learn more.

If you have upgraded from a previous version of Windows:

to Windows2000
  • Win2000 is essentially an NT program. Therefore, you may need to implement the Rainbow "service," i.e. follow the NT installation instructions.
  • Run D:\sentinel\drivers\setup.exe from the GSDS5 installation CD
  • This loads the files and starts the service.

to Windows XP

  • GSDS5 is not compatible with the Windows XP Professional edition but may work with the Home edition.
  • Install GSDS5. In the installation Wizard, make sure you choose to put an icon on desktop
  • Right click on the icon and select Properties
  • Click on the Compatibility tab
  • Set compatibility for Windows98
  • Follow directions/reboot if necessary and try again.

Spring Designer 2.1 drivers - Windows NT, 2000, XP

The support for this software has been discontinued. If you are getting error messages, you may wish to consider purchasing the latest SMI software, SMI's Advanced Spring Design Software.

Spring Designer 2.1 is a DOS-based piece of software and is more than 10 years old. Spring Designer was originally created before Windows was conceived and is not designed to run in a Windows environment. In many cases, the software simply will not function in the new versions of Windows.

However, in some circumstances, we have been successful in getting 2.1 to operate (although there are serious printer issues and printing may not be a pleasant experience).

Making the Spring Designer 2.1 function on NT or newer Windows operating systems requires downloading a new driver rom SafeNet (formerly Rainbow Corp.), maker of the security key that must be attached to the terminal's parallel port.

1) Go to the SafeNet's Sentinal Technical Support page:

2) Click on the Sentinel Protection Installer link.

3) Install the driver. It works on all current versions of Windows, including NT, 2000 and XP.

If this solution does not work, SMI unfortunately has no additional fixes for Spring Designer 2.1. You may wish to consider purchasing SMI's Advanced Spring Design Software.
