Note: While it specifically mentions Windows 11 and not Windows 10 it seems to run on most Windows 10 PC without any issues, however they are newer versions of Windows 10 so if you can't get it to work on your Windows 10 computer make sure that you have the latest version of Windows 10 installed. It's also worth making sure that you have a clean installation of the latest NVIDIA drivers as well so if you haven't done it for a while use Display Driver Uninstaller (DDU) to do that. Once you have new drivers installed you should have fewer Chat with RTX installation issues.

Fixing: Chat with RTX Error: NVIDIA Installer Failed Mistral 7B INT4 Failed.

At this stage, this is no 100% working solution for this problem and we are just waiting for NVIDIA to fix this error message. That said, I did have success trying to install it on the 3rd attempt. On the 3rd attempt, it installed fully without any issues so it's worth trying a few times until it does install. I suggest a restart somewhere in the mix as well if it still fails after 3 tries.
