# What does "Cloud scanning needs the built-in cloud engine, which isn't available" mean?

Checking cloud accounts relies on a component that ships inside the Storage Studio app. This message means the app couldn't use it, which usually points to an incomplete or damaged installation rather than a problem with your account.

To fix it, quit Storage Studio, download the latest version from the [install page](https://storagestudio.us/install), drag it into Applications to replace the old copy, and open it again. Scanning This Mac and iCloud Drive isn't affected. If the message persists, contact support from the app.
