# MDM App Installation Failure - User Not Registered for Managed Distribution

## Problem

When the user tries to install an iOS paid App from the App Catalog, an error message is displayed on the mobile device:

**"User Not Registered for Managed Distribution"**

## Cause

When the user tries to install a paid App from the App Catalog, the user will be prompted to accept an App distribution invitation. If the user fails to accept the invitation and tries to continue App installation, it means the user is not registered for Managed Distribution.

## Resolution

Users should follow the steps mentioned below to get themselves registered:

1. Open **App Catalog** on the managed device.
2. Touch the paid **iOS App** which needs to be installed.
3. Touch **Continue** to accept the invitation as mentioned below.

4. By accepting the invitation, the user will be registered for Managed Distribution. If prompted, users should provide their Apple ID and password. This is a one-time process, so users will not have problems installing a paid App distributed through Managed Distribution.

The user has now successfully registered for Managed Distribution and will be able to install the paid App from the App Catalog.
