Setting Up Chat with RTX on Windows

  • Launch the Chat with RTX application and accept the first prompt about Phyton. If it doesn't automatically launch you can open it

  • You'll be prompted to provide a local folder path. If it doesn't ask you can manually add a path using the Dataset section This is where the AI will analyze files. Choose a folder containing relevant documents such as Word, PDF, or text files. I suggest setting up one dedicated folder to use rather than giving it access to an entire drive or something. Allow the program some time to analyze the selected folder, as this process may take a while depending on the size of the files. If you don't set a folder it will give you a response like the one seen below.

Important Information about NVIDIA chat with RTX

While Chat with RTX is decent you'll probably get bored with it pretty quickly, but I do believe NVIDIA has some pretty big plans for it in the future. It's the kind of thing I can see them turning into a virtual assistant or something along those lines. The kind of thing that Cortana was supposed to be all those years ago. As we mentioned at the very start of this guide Chat with RTX is compatible with Windows 10 and 11. Though Windows 11 is preferred, and It requires 3000 or 4000 series Nvidia GPUs. You'll also need the latest Nvidia drivers installed. For the best results, you'll want hardware with at least 8 GB of vram, and 80 GB of free storage space.

At this stage, this is no working solution for this problem. We are just waiting for NVIDIA to Fix this error message. I did have random success trying to install it 3 times.... On the 3rd attempt it installed fully... So give it a go.
