Cuda Installation Available Resource Issue

I have been trying to install CUDA to get my local copy of Stable Diffusion working again. The problem is that I have limited resources on my C: drive. I am down to just under 3 GB of available space. I have the CUDA installer set to install this software on an alternate drive, but every time I try to install it, it asks me for an additional 8GB of space. I’m fairly certain it is writing temporary files to the C: drive, instead of the alternate drive.

I cannot create more space without removing vital software, so what I would like to do is create a symbolic link between whatever directory this installer is referencing and a temp directory on the alternate drive.

Can someone tell me what directory or directories are being created by the installer, and what else I could do to get this to respect the settings I gave it?
