Whenever I try to download CUDA, it always fails at “Nsight Compute”. I have a 5070 that says its CUDA compatible. I am trying to install version 12.8.1

I read an old topic, and it’s similar to my case ([CUDA v12.3 Installer Failed at Nsight Compute](https://forums.developer.nvidia.com/t/cuda-v12-3-installer-failed-at-nsight-compute/271741)), I saw that in the answers it mentioned having Nsight Compute already installed, but that doesn’t seem to be my case, because I’ve never installed it and I haven’t found it on my PC.

What should i do?

Please uncheck Nsight Compute in “Custom" installation firstly. And then install “Nsight Compute” separately.
