Oh, perhaps I did. I just Googled the name, and clicked a link to Github, paying more attention to whether it said 'CPU' than whether it said 'Chess'. It complains about clReleaseDevice in OpenCL.dll. There is nothing in the archive that suggests whether it is for Go or Chess, but I suppose that it says leelaz.exe instead of leelacz.exe should have been a warning to me.
Anyway, Louis, thanks for the link; this one worked out of the box. Interesting thing is that, first game I tried with it, it lost against Fairy-Max! At some point it had an enormous lead, and then it bungled it, and even managed to lose. (And it flagged as well, in the first 40-move session, but I did not have autoFlag on, so the game just continued):
