How to update

You can update Essentials L2 in three ways: from a USB flash drive, directly over the internet, or remotely from EasyMatch Quality Central.

Option 1 · USB flash drive
  1. Download the .hunterlab file onto a flash drive (for example, 2024.4.2.hunterlab, where 2024.4.2 is the version number).
    Tip: You can rename the file if needed. ColorFlex L2 recognizes it by file type, not by name.
  2. Insert the flash drive into the ColorFlex L2.
    • Essentials L2 automatically detects the file on the drive.
    • If the file is newer than the currently installed version, Essentials L2 displays a prompt to update.

    The update prompt appears when a newer version is detected. Tap Install Update to begin.
  3. Follow the on-screen instructions to complete the installation of the new Essentials L2 software.
Option 2 · Check for updates online

When the instrument is connected to the internet, Essentials L2 can check for available software updates directly.

  1. In Essentials L2, go to INSTRUMENT SETTINGS → GENERAL, then tap SOFTWARE UPDATE.
  2. (Optional) Enable "Check for updates on launch" to have Essentials L2 check automatically each time the application starts. This option is disabled by default.
  3. Tap the refresh icon under Available Updates to check for updates. If a newer version is available, follow the on-screen instructions to download and install it.
Option 3 · Remote install from Quality Central

Starting in EasyMatch Quality Central 2026.4 and above, you can push a .hunterlab update file to a connected instrument over the network — no flash drive required.

Requirements: Quality Central 2026.4 and above, and the instrument connected to Quality Central on the same network.
  1. Download the .hunterlab file to the PC running Quality Central.
  2. In Quality Central, go to Settings → Instrument Settings and select the connected instrument you want to update.
  3. Choose the remote update option and select the .hunterlab file to push it to the instrument.
  4. Confirm the update on the instrument, then follow the on-screen prompts to complete the installation.
