I would like to follow up on this issue. I wanted to verify whether rc2 would crash on my pre-AVX2 system, so I downloaded the installer and ran it. It informed me that I had an older version and asked me if I wanted to remove it, to which I said yes.
FYI, the installation directory of the previous dt was set to another partition (not C:). After installing rc2, a darktable-[version] folder remained with a uninstaller app inside. So, I ran that too. It left me with a bin and share. So, same as before. I could manually delete share but bin was impenetrable. This time, bin simply disappeared after a reboot.
I wonder why it gets removed only after a reboot and not instantaneously… It doesn’t happen with other uninstalls. I haven’t tried doing one uninstall only and rebooting to see if everything disappears after that. Right now, I am doing two uninstalls and some manual deleting and then a reboot. Maybe next time…
It is an OpenCL crash upon initialization inside IntelOpenCL64.dll and igdrclneo64.dll, so the problem is in the Intel OpenLC implementation.
You have mentioned that you have an Nvidia Quadro M2200 in the machine: IMHO you should install the Nvidia driver, and that is providing OpenCL and should work.
Is there any specific reason why you installed this Intel OpenCL?
My machine is a Thinkpad mobile workstation and the drivers are in factory state. I never bothered to inspect them in Windows actually, I use it only for CAD softwares and Photoshop. Nvidia drivers are installed. I do everything else on Debian. If it’s a problem of driver on my side, I will let it rest then. I develop and use dt on Linux
FWIW: on linux the intel opencl drivers are actually filtered out and you cant enable opencl with them. something similar is missing for windows I guess.
