# unsupportedParentBundleLocation

An error code that indicates the extension’s parent app isn’t in a valid location for activation.

```
static var unsupportedParentBundleLocation: OSSystemExtensionError.Code { get }
```

## Discussion

The expected location of a driver extension is in the `Contents/Library/SystemExtensions` directory of a macOS app. The app itself must be in one of the system’s `Applications` directories.
