## Installer Version 6.23

## Package Version 6.23

### March 2012

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

## 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)
- Windows 2008 R2

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

## Enhancements

- The Run-time Environment contains a number of enchancements to support Sentinel LDK (the next generation of Sentinel HASP).
- A number of minor issues reported in the 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 that were created with Sentinel HASP Business Studio 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 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.

## Issues Resolved

- Ref #8033: If you attempted to update the Sentinel HASP Run-time, and your protected application uses DataHASP, it was necessary to close the protected application before running the update.
(Resolved in version 6.22)
- MKS 146944, 147038: The License Manager would eventually lose track of the number of detached licenses for a given Product if the number of available licenses for that Product was changed to a value lower than the number of licenses currently detached.
