If one of the dependencies is already installed on your environment, but has been customized, then the OutSystems Platform checks if your version is compatible with the application you want to download. If you customized the API (public elements) on which the application relies, OutSystems Platform warns that if you install the application it will not run properly. This happens because the application depends on functionality that is not yet available on your environment.
If this happens, you can still download the application and install it manually on your environment. Click on 'Download' to download the application package, and then double-click on it to start the installation.
Once the application is installed, you can see that it has broken references: it depends on functionality that is not available in the environment.
