DCH drivers do not use the standard installation path for the NVML DLL.
Fallback test for alternate locations.

Bug fixed being confirmed by reporting user.

C:\Program Files\NVIDIA Corporation\NVSMI>nvidia-smi.exe -q Failed to initialize NVML: Unknown Error

Which doesn't bode well for me

Reinstalled drivers, several times. Issue intermittently fixed. But I'm fairly confident the issue is my end

It could be that you have a DCH driver that has been installed while the older non-DCH driver remains installed.
The only workaround to avert this situation on my end would be to first attempt DCH driver detection and fall back to non-DCH driver detection if that fails.
Uninstalling any of the older drivers should help rectify the situation.
Thank you for reporting this issue.

Appreciate the suggestion, I'll give it a go.

Thanks for a really nice tool as well 👍
