Introduction

This utility allows the installation/uninstallation of the 'Sentinel LDK License Manager' service and drivers. It enables the use of USB license dongles and Software Licenses (SL) management.

It can be used to install a Windows server as a license server with software licenses or USB network licenses (red dongles) or simply to easily update USB dongle licenses from a server/laptop/desktop where Charon-AXP/VAX/PDP is not installed.

It can be installed even if Charon-AXP/VAX/PDP is already installed.

Features:

• Easy installation/uninstallation of the driver
• Read license content
  • working even from a remote desktop connection (RDP) → this requires the utility to be executed as Administrator
  • highlights on license expiration date
• Removing a Software License (SL)
• Access to Sentinel Admin Control Center
• Access to update license utility
• Stop/start 'Sentinel LDK License Manager' service
• License expiration check with alerts sent as Windows Application Event or email or custom script

Prerequisites

• Powershell 5.1*
  To get the update, please open the page: https://docs.microsoft.com/en-us/powershell/scripting/windows-powershell/install/installing-windows-powershell
• .NET Framework 4.6 minimum installed, 4.8 recommended. Installed by default on Windows 10, 11, 2016, 2019 and 2022. For older versions of Windows, this has to be installed manually.

Installation

Display license content

Example with USB dongle

Example with cloned software license

This software license is in cloned state as confirmed by the Sentinel Admin Control Center:

Possible reasons for cloned state are detailed here: HASP Software Licensing restrictions.

Package version versus installed version

This option allows you to check if the driver version installed is more recent or not than the one provided with the license utility.

Stop/start Sentinel License service

This option is used to stop the 'Sentinel LDK License Manager' service if it is running or to start it if not.

Software License removal

A popup window is displayed containing the software license key id, please answer yes or no to delete it or not:

If at least one license is deleted, a request is made to restart the 'Sentinel LDK License Manager' service:

If a Charon emulator (service) is running, a confirmation is requested to force the restart:

Removing a software license does not erase the file, it is archived in %programdata%\CharonLicenseUtility folder with date/time as extension so that it can be restored in case of mistake.

License expiration check settings

Click the "License expiration check settings" button:

If the "License expiration check settings" button does not appear, this means you're using Windows 2008 with PowerShell 4.0 or 5.1 (does not work in both cases) or Windows 2012R2 with PowerShell 4.0 (to upgrade to PS 5.1, see Powershell version, upgrade, enabling scripts execution, tips and tricks). More recent Windows versions have PS 5.1 already installed and dotnet 4.6 minimum.

Click then on the "Create Scheduled task" button:

 If the task (same name, same folder) was already created using the previous PowerShell script (setup with command lines), you will be requested to remove it before using the new one.

Configure it as you need. If you need a custom script to be executed the "Edit script" button allows you to open it with notepad++ if installed, otherwise notepad. If the script does not exist, a skeleton will be created.

Before using the "Execute now" and "Test alert with forced date" options, it is recommend to setup the email settings in the next tab as by default only Windows Application Events are generated (source = CharonLicenseExpChk)

Email configuration example:

Notes:

• If you're using Office365, you can click on office365 preset button if you plan to use it, this will fill the SMTP server, port number and SSL fields automatically.
• When the password is entered, the "Save" button background becomes orange to remind you to click on it to encrypt and store the password (if a password is needed of course).
• Important note: use a dedicated account to send alerts, do not use your personal one (FYI: the password is encrypted and stored in the registry. It is valid only on the computer where it is stored and for the 'system' account only)
• If the Charon Log Monitor utility is installed on your server and email is already configured, after clicking on "Enable sending email", you will be prompted to copy the email settings from this utility.
• HTML mode is highly recommended.
• Subject tag allows you to add something relevant in the email subject like where it comes from.
• Email footer is optional.
• It is recommended to use the "Test email alert" button to ensure email settings are correct.

Once email settings are configured, get back to the "Expiration check general settings" tab and use the "Test alert with forced date" button, specifying a date (default is today+5d) that is less than the number of days in the future you specified (14 days by default) to ensure an alert will be created and run the test:

A popup will appear with the test results:

The received HTML email looks like this:

Browse HASP log files folder

This button appears only if "Write an Access Log File" and/or "Write an Error Log File" option are/is checked in the Sentinel Admin Control Center / Configuration option.

It opens the folder "C:\Program Files (x86)\Common Files\Aladdin Shared\HASP" using explorer.exe.
