"An error occured while downloading and installing dependencies"

Title; Couldn't locate log file, I do use a VPN and tried it on and off. Will upload logs if I can find them before any replies, otherwise will wait for instruction

I had this issue too, I tried a whole bunch of random fixes that had apparently worked for others but the easiest solution was to download it from here: https://www.nvidia.com/en-us/ai-on-rtx/chatrtx/ and install it.

note: on my install it paused once with a firewall request which I chose to allow - the install subsequently worked fine and I have moved on to other issues (hah)

I've slowly been doing troubleshooting tricks on this for my computer, and I found that by removing ctype from the requirements file will allow you to install some of the missing dependencies that it missed in the NVidia installer:

cd "C:\Program Files\NVIDIA Corporation\ChatRTX\RAG\trt-llm-rag-windows-ChatRTX_0.4.0"
....\env_nvd_rag\Scripts\pip install -r requirements.txt

One I did this the error evolved into this one:
