LAStools won't run in Qgis

Can't run LAStools in Qgis or as Standalone

I believe I have successfully installed latest version of LAStools in Qgis 2.8.2 as they appear in the Processing toolbox, and I get a dialogue box when I run them. However, I get no output. For a few times, the dialogue box just closed when I clicked "run". Now it doesn't close, but the progress bar remains at 0% when the process completes, and then I get a "no output" error.  I test ran geoalgorithms in the QGIS and Orfeo toolboxes and they ran fine.

I also tried to run LAStools as stand alone program, but the dialogue box freezes when I click to accept the pop-up license agreement.

Any solutions would be appreciated. I'm converting LiDAR data into basemaps for our Orienteering Association. I'm new to Qgis, LAStools and don't have scripting skills. I've worked a little bit with LiDAR data though, and it was pretty straight forward using Global Mapper for generating contours from the data, but I'd like to use LAStools if I can, especially for classifying vegetation as I'd like to use the scripts made by Terje Mathisen for making orienteering basemaps.

I'm running Windows Vista SP2 with 32bit / P8400  2.26GHz / 3gigRAM (don't think it's an issue though).

Hello,

there are a number of discussions on this issue that only seems to affect a select few people. Maybe read through the comments of some of these threads:

Thank you Martin.

I have been through most of these posts several times. It would appear that my problem may be somewhat unique and related to my computer setup. I've uninstalled an aggressive firewall, and uninstalled QGIS 3 times in order to start over fresh. The mysterious thing is that when I run a LAStools as stand alone program it freezes up when I click to agree to the licence. I tried a LAStool as stand alone on an old computer running XP and it didn't freeze. Of course XP too old and slow to process anything, let alone to install QGIS on.

I have to give up on my system for the time being, but I should be able to assist a couple of our other mappers to get LAStools up and running.

Thanks again
Bryan
