# Understanding App Installations

What happens when Marketplace apps are installed? What determines whether an app installs successfully or fails? Is there anything I can do to make sure the app installs successfully? If an app fails during an installation, is there a way to see why and even fix it? These are only some questions you’re probably asking yourself when installing Marketplace apps. This section explains how to troubleshoot and fix errors that occur when installing apps.

- **[App Installation Statuses](https://help.salesforce.com/s/articleView?id=mktg.dato_mark_app_installation_status.htm&release=264.0.0&type=5)**  
    When an app starts to install, two synchronous steps occur during installation. These steps affect the installation status of the app.
- **[Failed Apps and Their Implications](https://help.salesforce.com/s/articleView?id=mktg.dato_mark_app_installation_failed_apps.htm&release=264.0.0&type=5)**  
    Apps don’t always install successfully. Sometimes there’s an issue with the app, or the processing of the underlying entities. For example, the provider timed out, the app installation timed out before the underlying entities were processed, or even due to invalid mapping.
- **[Fix a Failed App](https://help.salesforce.com/s/articleView?id=mktg.dato_mark_app_fix.htm&release=264.0.0&type=5)**  
    If an app fails during installation you can explore and find out why this happened. You can see which processes must be fixed to install the app, and those that can be fixed at a later date.
