# What does "App could not be installed at this time" mean? This is a broad error description and can occur for various reasons. We recommend you verify the following things: * The app is signed with a valid *Ad Hoc* or *Enterprise* certificate * If you are using an *Ad Hoc* certificate, the device UDID is registered for the provisioning profile that was used * The deployment target (minimum required iOS version) is not higher than the iOS version on the device * The app is configured to run on this device family (iPad OS apps may not run on iPhone) * There is enough free space on the device to install the app Try these steps until you find the source of the error. It can also help to remove all currently installed versions of the app and reattempt the installation. If you are still having trouble getting the app to work, feel free to [contact us](https://docs.getupdraft.com/contact) and we'll do our best to help you out. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
