We are back again at the error message in the first post, correct?
Most search results from the internet point to problems with the Python installation, so you could try reinstalling Blender and/or uninstalling all other Python installations on your PC.

However, first to make sure: You do have a 64 bit Windows, right? Our builds don't work on 32 bit machines.

no worries. everyone needs a timeout at some point yes it is the first error message again. i will try to do so but this might take a while till i can try this. and sure i got 64 bit windows 8

so i uninstalled all python related installations and reinstalled blender but the errormessage remains the same.

Problem solved for me!

Couldn't start Luxmark because "OpenCL.dll" was missing, so the problem was obvious that there must be a problem with the display driver. Reinstalled it and now I can activate Lux OCL. Phew! Thanks for the support. Maybe the error handler could be improved here, as this took a real long time for me to toubleshoot. And as per google there are a few more out there with that issue.

now that I can use my GTX 1070 with OpenCL its sooo darn fast! yeeehaaaa

Hm, searching on the net doesn't really bring up anyone with this exact problem.
Maybe some other program messed with your system's PATH or PYTHONPATH environment variables?
I think it's something very specific to your system.

This thread describes something quite similar to your problem:

Are other blender add-ons working for you?

You could try to rename folder "C:\Users\Antony\AppData\Roaming\Blender Foundation\Blender\2.79", then reinstall BlendLuxCore.
You will lose also your blender preferences and other add-ons you have installed, but it may be worth trying (you can always recover from the renamed folder if necessary).

I've installed in another computer (@ home) and I had the same problem on addon activation. (@work all is fine)

Yesterday I've solved just installing the Intel "thing".
Today I've tried again and Luxcore failed to load.
So I've tried to install Visual Studio thing but nothing solved.
I've tried to reinstall the Intel thing and now Luxcore is working.

I really can't understand why I've to reinstall it.
Have you something to suggest?

Yes other addons do work fine for me. But i had similar Problems activating the growth nodes addon. You mean that i just rename the 2.79 folder? If it does not work for luxcore can i just rename it back to 2.79 and it will work like now? Asking because i Installed quite some addons on 2.79 ^^.

Yes, for example to "2.79_backup".

Yes.

Hi, your problem seems to be different than in the other thread, but you will need to install the VS 2017 redistributable anyway: https://aka.ms/vs/15/release/vc_redist.x64.exe
