This usually happens because the main Download button on the Marketplace page is not active for this module. The SMB Connector is an older module, so the top Download button can appear non-clickable.
Instead, go to the Releases tab and use the Download link on the right side of the release version (for example V1.0.0 → Download). That link should allow you to download the module.
If this resolves the issue, please close the topic.

If you still want to use the module, you can follow this approach:
Hope this helps!
