I've had no problems installing LuxCore for blender, and updating Luxcore from inside Blender when updates are ready.

However, this time it did not work.
When trying to upgrade from 2.0 to 2.1alpha1 I get errors (missing embree3.dll?):

I did one thing wrong, I forgot installing Intel C++ redist. But I've now tried with it. Exact same result (errors).

Thank you.

With new Embree v3.2.0, Intel has changed the name of the DLL from "embree.dll" to "embree3.dll" because Embree v3.x API is not compatible with Embree v2.x API.

The .zip you linked (https://github.com/LuxCoreRender/BlendL ... opencl.zip) includes the correct "embree3.dll".

Can you check if the DLL is present inside your "C:\\Users\\Steinar\\AppData\\Roaming\\Blender Foundation\\Blender\\2.79\\scripts\\addons\\BlendLuxCore\\bin" directory

That was a fast reply, thanks.
I had embree3.dll in the wrong path, figured it out, but you already replied. I feel stupid for not trying more before crying about it here.

Thank you for your hard work, it's really appreciated!

Edit:
Just in case it matters for anyone; The autoupdate did not work, I have no idea why it did not install embree3.dll correctly.
I got embree3.dll from Intel-sources (Yes, after your reply I know realize it's also in the .zip the autoupdate downloaded, why it didn't install it automatically I don't know).

So I had to manually copy the DLL to where it belongs, I guess I did something wrong or my system is werid/corrupted - because noone else have encountered this problem of missing embree3.dll when autoupdating.

It is a bug in BlendLuxCore, in this line:
https://github.com/LuxCoreRender/BlendL ... ate.py#L50

I will fix it later.
