Lightroom denoise function error.

Nvidia GTX530

That is very old GPU. Released back in 2011. Looking at NVIDIA driver support page, Last driver was released back in 2018. Looks like NVIDIA has it in legacy status (i.e. no new support)

It also looks like it has no more than 1024 MB of memory if the OEM model, well below LrC GPU support minimum for AI. It might have 2048 MB by some mfg's. And that is are bones minimum and iffy for LrC AI

And it has a GPU benchmark of 1276, below the Adobe minimum recommendation of 2000.

You need a better GPU
