Update Device Scout

Upgrade Device Scout in place when a new version is released, so printer discovery and data collection keep working with the latest fixes. The updater keeps your existing registration and settings.

When to run	When a new Device Scout version is released
Owner	IT administrator
Impact on users	None for people printing, because updating Device Scout doesn't change the Local Connector.

Before you begin

You have administrator rights on the server where Device Scout is installed.
To download from the web console, you have the Site Encryption Key. See Save or recover the Site Encryption Key.
You've backed up the Device Scout logs, configuration and registration folders, in case you need to roll back. See Roll back to the previous version.

Steps

Get the new version

Use either of these:

From the web console: go to Discover > Device Scout, select Create, enter a name and select Save. Then select the new Device Scout, select Download and enter the Site Encryption Key. Each Device Scout has its own registration key, so you create a new one each time you update. See Create a Device Scout and Download Device Scout.
From the updates page: download DeviceScoutUpdater.zip from the HP Release Versions and Updaters page.

Copy, unblock and extract the file

Copy the ZIP file to the server where Device Scout is installed. Right-click it, select Properties, and select Unblock if it's shown. Then extract it to a local drive.

Run the MSI installer

Run AgentInstaller.msi as an administrator. In a package downloaded from the web console, it's in the Msi folder. The installer finds the installed version and upgrades it in place.

Use the MSI file, not Setup.exe. The MSI is what detects the existing installation and upgrades it reliably.

Delete the old record

If you downloaded from the web console, the old Device Scout record stays on the Device Scout page. When the new Device Scout shows OK, delete the old record so it isn't mistaken for a Device Scout that has stopped working. The printers it discovered are kept. See Delete a Device Scout.

What good looks like

The Device Scout service is running in Windows Services.
On the Discover > Device Scout page, the updated Device Scout shows OK and its Last Heartbeat is current. If you created a new record, it’s the new record that shows this.

NoteUpdating Device Scout doesn't update the Local Connector (Secure Print Service), even if you installed them together with Setup.exe. Update it separately. See Update the Local Connector.

Roll back to the previous version

If the new version doesn't work, go back to the last version that did.

Back up the Device Scout folders

If you haven't already, copy these folders somewhere safe:

C:\ProgramData\HP\DeviceScout\Logs
C:\ProgramData\HP\DeviceScout\Registration
C:\ProgramData\HP\DeviceScout\Configuration

Uninstall Device Scout

Uninstall the new version. The Configuration and Registration folders are kept, so you don't need to restore them.

Reinstall the previous version

Install the previous version with its MSI file, then restart the server or the Device Scout service.

If something goes wrong

If the Device Scout doesn't show OK or its heartbeat stops, see Device Scout or Print Scout isn't working.
If you contact Support, include the logs from the Logs folder. See How to troubleshoot.
