If your Lumo Play installation crashes when using the Intel RealSense D415, D435, or D435i camera with a 2x00004000 error code you can resolve the issue fairly simply by installing the updated Microsoft Visual C++ 2015 runtime, and by optionally updating the firmware on your RealSense device.
1- Update the Visual C++ 2015 Runtime
First, make sure to download and install the Microsoft Visual C++ 2015 Runtime update available here. Click on the download button and select both the 32-bit and 64-bit versions:
Click the "Next" button in the lower-right corner to begin the download. Once the files have downloaded, double-click on each one to install the update.
2- Check for Firmware Updates
Once the Microsoft Visual C++ 2015 runtime is updated, you may wish to check if there are firmware updates available for your RealSense camera. To begin, download the official RealSense viewer ("Intel.RealSense.Viewer.exe") from this page.
With the RealSense connected to your computer, double-click on the program to open it. If a firmware update is available, a notice will appear in the upper-right corner of the application:
RealSense Viewer will download and install the new firmware to your camera. If you have multiple RealSense D400 series cameras, make sure to install firmware updates on all of them.
