Troubleshooting

Things you can check/try (not all things will apply to your issue):

(You don´t need to try everything, just read the following list of probable causes and see if something rings true for you)

• make sure the downloaded Meshroom files are not corrupted (incomplete/interrupted download)

• you have to extract the archive and not just launch it from the zip viewer. If you have a path like this on windows: "C:\Users\DEV\AppData\Local\Temp\meshroom", you are in the temp folder of the zip viewer. #600

• using remote drives under windows or access restrictions may cause unexpected GUI problems. Place the Meshroom binaries in a directory without special restrictions (If you are not familiar with folder permissions, on windows the "My documents" folder is known to work.)

• avoid special characters/non-ASCII characters in Meshroom and images file paths (#209)

• make sure your antivirus program does not interfere with Meshroom ((#178)/(#342))

• are you running Meshroom as Admin? Don´t. (This will disable drag-and-drop on windows) #599

• Check your Python installation /reinstall as admin and check the PATH if there are any conflicts

• update/install latest NVIDIA drivers Sometimes Windows updates mess up Nvidia drivers, replacing the Nvidia driver by a generic driver, causing the DepthMap Node to fail. https://github.com/alicevision/meshroom/issues/1397

• set your NVIDIA GPU as primary GPU for Meshroom. (NVIDIA Control Panel->Manage 3D Settings)

• Try the Meshroom 2018.1 release; when using windows 7 try the corresponding release (Meshroom 2019.1 has some problems with Texturing #449, DepthMap and some photo datasets which worked in 2018.1 #409. These problems should be resolved in 2019.2)

• Test Meshroom with the Monstree dataset

• Sometimes the pipeline is corrupted. Clear the cache for the node (and following nodes) with the error. Sometimes restarting the application / the computer might help. #201

• check your images for problems

• Windows 10 stores your Pictures folder in your user profile. You may get problems copying this path. Use another folder and copy the full path.

• Install Visual Studio 2015, 2017 and 2019 to solve the VCOMP140.dll not found error #840

• Windows N version (which is used in most Azure VMs) does not contain the Windows Media Feature Pack. You need to install it to solve this error "The code execution cannot proceed because MFPlat.DLL was not found." #1108

• disable all driver/system modifications that could interfere with Meshroom, like CPU/GPU overclocking or drivers that interact with the hardware resources. When opening a bug request, please mention this non-standard system modifications. This is an issue that can occur in such a case: https://github.com/alicevision/meshroom/wiki/DepthMap-slow-or-red-bar-or-crash#depthmap-crash--freeze
