Medmont Meridia™ impacted by Windows 11 update

February 13, 2025

No action required if you are not running this update or if you have already run this update and not experienced the issue described below.

A bug in Microsoft Windows 11 update version 24H2 (January 14, 2025) is likely to cause Medmont Studio 7 to not properly communicate with the Medmont Meridia™ camera. 

Please note: This issue does not affect E300 topographers or M700 perimeters.

To address this issue, Microsoft instructs that if you are installing Windows 11 24H2 (KB5050009) then you must also install KB5050094. 

After doing the above, if Medmont Studio has a connection error when trying to perform topography, perform the following check and recovery steps.

We encourage you to resolve the problem yourself or with the assistance of your IT support. If you need further assistance, please contact your local Medmont distributor (if you are outside Australia) or Medmont Australia. (Support from Medmont Australia attracts a technical support fee.)

Check the Windows Update History to see if the 24H2 update is installed:

Alternatively, launch the “System” control panel from the Windows search bar and look for the version:

How to solve the issue yourself:

  1. Open Windows Device Manager as Administrator
        a) Open Device Manager – Microsoft Support.
  2. Locate the camera device.
        a) The camera device will appear differently depending on the camera type in your Meridia.

b) Right-click the camera device → “Properties” → Driver tab → Uninstall Device →☑ Attempt to remove the driver for this device (if this appears) →Uninstall

c) Run the Medmont Studio Configuration Tool to completion, accepting default responses.

d) Disconnect the topographer from the USB port and reconnect it to the same or another suitable USB 3 port. Alternatively, restart the USB port in Device Manager or USB Device Tree Viewer. The affected driver should then reinstall correctly.

e) If you still have problems, contact your Medmont Distributor (international) or Medmont Australia. Contact details can be found here.
