Application Resilience policies for Dell Trusted Device

You can activate an Application Resilience policy for Dell Trusted Device to collect information about the functional status of Dell Trusted Device installed on your Windows devices and view the results in reports. You can also configure the policy to attempt to repair or reinstall the application.

Application Resilience policies for Dell Trusted Device are supported on devices running:

  • a supported version of the Windows operating system

  • PowerShell version 5.1 or higher

    Due to PowerShell restrictions imposed by Microsoft, Application Resilience isn't supported for this application on devices running Windows 11 SE.

  • one of the following versions of Dell Trusted Device:

    • 6.x or higher (requires ASP.NET Core Runtime 6 and .NET Desktop Runtime 6)

      Significant software changes in higher versions may cause health checks to become invalid.

    • 4.x to 5.x

In addition to checking the version, the following table describes the health checks performed:

If you select Report higher versions as Compliant, higher versions report Compliant without running health checks.

The application uses one of the following names:

  • Dell Trusted Device Agent

  • Dell Trusted Device

You can configure an Application Resilience policy for Dell Trusted Device to enable the Application Resilience (RAR) component A lightweight software component of the Secure Endpoint Agent that detects the status of third party applications installed on a device. The component may also attempt to repair the third party application if it is non-compliant. The RAR component is deployed on a device only when the device is associated with a customized policy group and that policy group's Application Resilience policy is activated. to attempt to repair Dell Trusted Device if it's not functioning, or reinstall it if it's missing or can't be repaired.

Depending on the Absolute product licenses associated with your account, the Report and repair and Report, repair, and reinstall options may not be available.

The RAR component of the Secure Endpoint Agent can respond to the following issues:

Issue Resolution
Repair
The Dell Trusted Device (Dell.TrustedDevice.Service.exe) service isn't running

The RAR component restarts the service.
The Dell Trusted Device (Dell.TrustedDevice.Service.exe) service isn't installed and the service's executable can be detected on the device

The RAR component reinstalls each missing service.
Reinstall

Downgrades are not supported. If the version installed on a device is higher than the expected version, no action is taken.
The Dell Trusted Device (Dell.TrustedDevice.Service.exe) service isn't installed and the service's executable cannot be detected on the device

If the application is installed, the RAR component uninstalls it. After the application is uninstalled, or if the application wasn't installed, the RAR component downloads and installs the configured version of the application.

A device restart is required after the application is uninstalled. The Secure Endpoint Agent doesn't force the device to restart, so a status of Not Compliant continues to show in the Application Resilience reports until the device user performs a restart and the configured version of the application is downloaded and installed. You can review the report's Status details to determine if a restart is required.

In some cases, Dell Trusted Device doesn't detect that the device has been restarted. In these cases, a second restart is required before the RAR component can reinstall Dell Trusted Device.

One or more of the following device drivers aren't installed, or aren't functioning correctly:

  • BIOS Verification Driver (DellBV.sys)
  • Dell Secure Event Log (dtdsel.sys)
Dell Trusted Device failed to be repaired, or the expected version isn't installed

If you want the Secure Endpoint Agent to reinstall Dell Trusted Device if it is non-functional or missing, you need to make its installer available for download. The installers are included in Trusted Device installer ZIP file. To make the installer available, you need to extract them from the ZIP file.

To prepare the installer:

  1. Copy the Trusted Device installer ZIP file (Trusted-Device-<version>.zip) from the installation media to your computer.
  2. Navigate to the location where you saved the ZIP file and extract the contents to the location you want to store the extracted contents.

The Win64R folder contains the 64-bit MSI installer. WinNtR contains the 32-bit MSI installer. The MSI files in these folders can now be uploaded to the Secure Endpoint Console or hosted on your own server.

If you host your own installers, make sure you provide the location of the MSI files, and not the location of the ZIP file or it's subfolders.

The RAR component looks for the following files names when checking pre-cached installers:

Component File name
Installers DellTrustedDeviceAgent.msi

Before you activate an Application Resilience policy you need to configure the policy. In addition to the settings in Configuring Application Resilience policies, you need to configure the application version.

  1. Under Application version, select the version range that should be running on your devices.

  2. Under Dell Trusted Device version, enter the version of Dell Trusted Device you expect to be running on your devices.

  • The target version must be a sequence of digits separated by a period.
  • You can use wild card "*" characters after the major version, for example, 6.* or 4.5.*.

Make sure the version you are entering is consistent with the version range you selected.

If you selected the Report, repair, and reinstall option, you also need to configure this setting in addition to the settings in Configuring Application Resilience policies.

  1. [Optional] To only reinstall the application if it's missing, select the checkbox next to Do not reinstall or upgrade if the app is already installed. When this option is selected, the application is not reinstalled when either of the following conditions apply:

    • The application version is lower than the expected version.
    • The application can't be repaired.
  1. [Optional] Under Additional installation commands, enter the applicable installation command-line parameters to configure any settings not covered by the policy configuration. For more information on available parameters, see Dell's documentation.
