As of Bottles version 51.24, which is the latest on Arch Linux at least, some of the components couldn’t be install normally. In order to see what’s the error message, I started Bottles from a terminal:

flatpak run --command=bottles com.usebottles.bottles

This is really handy for troubleshooting anything. When I clicked on the download icon I saw it’s actually just a 404 under the hood.

To fix this issue, for vkd3d-proton, the release file changed it’s file extension from .tar.gz to .tar.zst. The download link can be found here. And the downloaded archive should be extracted to

~/.var/app/com.usebottles.bottles/data/bottles/vkd3d

Similar for dxvk-nvapi, the release file can be found here and should be extracted to

~/.var/app/com.usebottles.bottles/data/bottles/dxvk-nvapi

There’s already a GitHub issue here. Hopefully it can be fixed in code easily.
