LuxCoreRender Forums

I've been trying to install LuxRender for awhile now, but keep running into the same issues. I get two errors each time I try to enable the add-on.
First: This CUDA error Second: I've tried this both with luxcore 2.4 and 2.5 beta. I've also tried it on Blender versions 2.8, 2.9, and the most recent 2.91.2 (after reinstalling).
I've updated my graphics card. I have Visual C++ Redistributable Packages for VS 2017 and Intel C++ redistributable installed. I've got an AMD Ryzen 5 3600 6-Core Processor and a Radeon RX 5500 XT GPU.

Luxcore 2.4 works on my home pc (intel 7 and intel integrated graphics) but does not on my work pc, where I really need to get my renders done. Please help, I'm at a loss for what to do.

It is a CUDA error but you seem to not have a NVIDIA GPU. You may have NVIDIA driver installed (from a past GPU now removed ?): just remove the unused NVIDIA driver.

That was exactly the problem. Used Device Manager to find the hidden driver and uninstall it. Thank you so much!
