Have you installed the libraries listed at the end of the message viewtopic.php?f=9&t=630 ?

NOTE: Thanks to Acasta69 work, this release for Windows is compiled with VisualStudio 2017. You may need to install the VS2017 runtime libraries: https://support.microsoft.com/en-us/hel ... -downloads

NOTE: due to a bug (https://github.com/embree/embree/issues/195) in Embree v3.2.0, you need to install
also the Intel C++ redistributable (https://software.intel.com/sites/defaul ... .3.210.zip) on Windows

Are you using the OpenCL version ? Is LuxMark working ?

Ok, you will have to investigate what DLL you are missing. Download the stand alone version from https://github.com/LuxCoreRender/LuxCor ... opencl.zip
Unpack the .zip and run the luxcoreui.exe, you should get an error (post the message here, please).

You can than use a tool named Dependecy Walker to check what DLL you are missing, the procedure is described here: viewtopic.php?f=4&t=640&p=6412&hilit=de ... lker#p6407

When I launch LuxCore UI there is no error.

after checking "luxcoreui" with dependencywalker

This mean the problem is python related. Are you sure to use the official Blender 2.79b (Python v3.5) and not a daily build or v2.80 (Python v3.6) ?
