I want to use QGIS 3.4.13 to convert las files into xyz-text files.

So far I installed the LAStools Toolbox in QGIS and I think I can use the las2txt tool for the conversion. However I get the error message

The system cannot find the path specified

According to this link I'm supposed to download the LAStools Software from here. However, the software requires to pay a licence fee (pricing), but I am looking for a cost free solution.

In this chat a user said:

I would suggest using an open source tool. LASTools is a great open source tool for handling and converting LAS files.

You would need to use the LAS2TXT function and you could get an ascii text file of the lidar data.

Thus, this particular tool is for free after all? But then why do I get the error message?

Perhabs there is an alternative to LAStools to convert las data into xyz?

    If you are not restricted to use QGIS, I would recommend SAGA GIS for this task. There you can import LAS files, create subsets and export point clouds to xyz files. – Stefan Feb 25 '20 at 10:37
  • Give a look to this question. It is a bit older but i think that discuss the same problem in LAStools, gis.stackexchange.com/questions/191590/… – Val P Feb 25 '20 at 10:59

    If you read the LICENSE.txt you could find "There are TWO parts to LAStools. One part is OPEN source (LGPL 2.1). The other part is CLOSED source and requires licensing for most commercial or government use. " LAS2TXT is "free" open-source LGPL – Marco Feb 25 '20 at 11:05
  • The answer gis.stackexchange.com/a/307213/36393 is a good one, did you change the LASTool folder? – Marco Feb 25 '20 at 11:09

The default folder for LASTool is C:\LASTools.

You need to change the actual destination manually.
