SCCM 2012 – Detection Method for Update

Posted on by

With Configuration Manager 2012, you have a new feature to deploy your software: Application. To use Application, you need to add a Detection Method. This detection method is based on several criterias and it will check if the application is already installed on the computer.

SCCM included three built-in detections:
