Claro gets installed as a background process (called “service” on Windows and “Daemon” on Mac OS X and Linux platforms). If installed with default settings, the service/daemon will start automatically at system boot. It will monitor the hotfolders and process images regardless of whether the user-interface runs or not.
To access folders on the network, it needs read and write access to those folders. For this reason it is important with which user account the service/daemon starts. On Mac OS X, it will run with the user-account that was logged on to the system to install Claro.
On Windows, you have the opportunity to choose a user-account and specify the password during installation. The installer checks whether the username and password are correct and can actually be used to start the service. If you leave those fields blank, the service will run with local system account. The local system account on Windows never has access to the network. Even if the network folders have “full control” acces for “everybody”, Claro will not be able to use those folders if it runs with local system account. You can change the logon of the service in the Windows services control panel as shown below. Flows will be put on standby automatically if the input folder is not accessible.
