Update for Windows tablets (Windows / Getac)

This guide describes how to manually apply an update to tablets (Getac or other tablets running Windows) using a USB drive. 

🔎 Why This Update Is Required

When upgrading from a version earlier than 1.21.0 to version 1.21.0 or newer, a one-time manual operation is required.

This is due to the expiration and replacement of our previous code signing certificate. The change affects how Windows validates the app and temporarily breaks the automatic update mechanism (trough the eHub) on Windows-based tablets.

Once this manual step has been completed, automatic updates will resume working as normal going forward.

🔄 What the Update Does

• Uninstalls any previously installed version of the application
• Installs the new bundled application version
• Installs the required root certificate for offline validation
• Updates references to the new App ID
• Fixes shortcuts and startup scripts to reflect the new app identity

🔧 What You Need

• Dowload files here   (Please contact W5 for password)
• USB stick with update files (extract to the root folder of USB stick)
• Powered-on tablet (eScore-eMonitor can be running)

📘 Step-by-Step Instructions

1. Insert USB stick
   Plug in the USB drive to the tablet. File Explorer should open automatically.
2. Run the script
   Double-click LaunchCertificateAndAppIDFix.bat from the USB drive.
3. Allow administrator access
   A prompt will appear:
   “Do you want this app to make changes to your device?”
   Click Yes to proceed.
4. Script executes modifications
   The script will:
       •    Install the required root certificate
       •    Update app identifiers
       •    Fix shortcuts and startup scripts
5. Complete the process
   When prompted, you can either:
       •    Press Y and enter to reboot
       •    Or close the window to exit without reboot, or Press N and enter
   Tip: To bring up the on-screen keyboard, double-tap near the prompt text.
6. Device reboots automatically
   After reboot, remove the USB stick. The monitor is now updated.

⚠️ Important

If any error occurs during the process:
    •    An error message will appear
    •    An alarm sound will play (if audio is enabled)

If you encounter an error message indicating missing dependencies, this can be resolved by running a dedicated installation script.
On the USB stick, you will find a folder named /utils. Inside, there is a file: eMonitorInstallWithDependencies.bat
This script will install any required dependencies and ensure the application runs as expected.
Run this script the same way as the other one (double-click and allow administrator access), and then follow the on-screen instructions.
