fileNotFound error

I installed chroma in a conda environment. I registered the API key via this code:
from chroma.utility.api import register_key
register_key("[mytoken]")
When I try to run a simple program such as:
from chroma import Chroma
chroma = Chroma()
I receive this error message:

Did I not register the API key correctly, or is this another issue such as it being in a conda environment?
Hey, Can you check first you if have the permission to write to /tmp/? I think RCSB_file_download failed silently due to lack of write permission.
Oh, we just realized you are on Windows, and /tmp/ probably does not exist
on windows. Will figure out something.
Okay thanks. Yea I wasn't sure if that was the problem. I was trying to look at file paths, but I didn't want to mess with them and screw anything up.
While we are working on taking out hard coded path, you can also try Windows Subsystem for Windows to have a local linux environment.
Hi! We pushed a fix which should help with the temporary directory issue on Windows. Would you be able to pull and try again?
