I have a problem with LAStools in QGIS 2.14. I've followed the LAStools instructions for downloading LAStools for QGIS. `

I replaced 'lidar' folder in C:\OSGeo4W64\apps\qgis\python\plugins\processing\algs\lidar with the folder downloaded from http://rapidlasso.com.

I downloaded the 'LAStools' folder and put it in the following location: 'C:\LAStools'. I activate LAStools in to Processing, and type 'C:\LAStools' for the 'LAStools folder location', but I get the following message:

"Wrong value for parameter "OTB applications folder": Specified path does not exist: C:/OSGEO4~1/apps\orfeotoolbox\applications"

LAStools appears in the processing toolbox. I can start to run a lasview. The data appears in 'just a little LAS and LAZ viewer', but the program hangs and then crashes.

Is this happening because of the error message? I have looked through the StackExchange for other examples of this specific problem, with no success. Any suggestions on what am I doing wrong?

  • Thanks Andre Silva. I'm afraid that post does not address my problem. In that case user33103 could not open the LAStools plugin or enable the toolbox. I can do both. In my case, I get an error message when I follow instructions to enable LAStools in the toolbox, and Lasview just seems to hang and crash. Any suggestion?

For the latest version of QGIS 2.14 there should be no need to replace the 'lidar' folder in C:\OSGeo4W64\apps\qgis\python\plugins\processing\algs\lidar with the folder downloaded from http://rapidlasso.com/LAStools. This was only needed in earlier versions up to QGIS 2.8. For newer versions just do step 4 and then continue with step 6 of the install instructions from this older blog article.
