If you are running Langflow Desktop on Windows, you must [enable Developer Mode](https://learn.microsoft.com/en-us/windows/apps/get-started/enable-your-device-for-development#activate-developer-mode) to use the Docling components. The location of this setting depends on your Windows OS version. Find **For developers** in your Windows Settings, or search for "Developer" in the Windows search bar, and then enable **Developer mode**. You might need to restart your computer or Langflow to apply the change.
