# Sentinel® LDK Run-time Environment Installer GUI: Readme

This document provides information regarding the Sentinel LDK Run-time Environment Installer GUI, including supported operating systems, enhancements, and known issues. ("Sentinel LDK" is the next generation of the Sentinel HASP system.)

## Version 6.21 (November 2011)

### Operating Systems Supported

- Windows 2000
- Windows XP (32-bit and 64-bit)
- Windows Server 2003 (32-bit and 64-bit)
- Windows Vista (32-bit and 64-bit)
- Windows 2008 (32-bit and 64-bit)
- Windows 7 (32-bit and 64-bit)

Note: Windows XP Embedded is not supported with this installer. To install the Sentinel LDK Run-time Environment under Windows XP Embedded, use the SLD file.

### Enhancements

- Sentinel LDK Run-time Environment contains a number of enchancements to support the next generation of Sentinel HASP.
- A number of minor issues reported in Sentinel HASP Run-time Environment have been resolved.

### Changes in Terminology

Sentinel Admin Control Center user interface and help files incorporate changes in terminology as follows:

- The Sentinel HASP product is now referred to as Sentinel LDK.
- HASP keys are now referred to as Sentinel keys.
- SL keys now appear in the user interface as "SL-Legacy" keys.
- References to Sentinel EMS in the help files are also valid for Sentinel HASP Business Studio.

### Installing the Run-time Environment

- The Installer GUI detects the version of the operating system during Run-time Environment installation, before installing the relevant drivers.
- By default, Windows 7, Windows Vista, and Windows Server 2008 (R2) operating systems display a User Account Control message during driver installation. The user must click Continue to continue the installation. Alternatively, the user can change the default setting from the Control Panel of their operating system.

### Upgrading the Run-time Environment

When using the Installer GUI to upgrade the Sentinel LDK Run-time Environment, ensure that:

- No other Run-time Environment Installer is active.
- No other Run-time Environment components are active. Although the installation program terminates applications that are accessing the Run-time, it does not terminate running services. For example, if the Sentinel License Manager is running as a service, you must stop the service before upgrading the Run-time Environment.

### Limitations

- When using Win32 HL Envelope-protected applications using Sentinel LID Data Encryption facility or overlays that run on Windows x64 operating systems, you must unmap any memory-mapped files prior to closing the application to prevent possible data loss.
