DJ.Studio’s Stems feature requires a separate extension that must be installed before it can be used. This extension is managed via Settings > Extensions.
On some systems DJ.Studio isn't able to install the extensions. Most of the time, this is due to blocked network access of DJ.Studio.
Installation and Network Requirements
Separate Extension: The Stems feature depends on an extension that isn’t bundled with the main app.
Network Access: On some systems, installation can fail—often because DJ.Studio is blocked from accessing the necessary network resources.
If you are on a secured network (such as at work) or using a machine with strict security settings, ensure that DJ.Studio isn’t blocked from reaching these URLs.
