If the DICOM Viewer has already been launched, you cannot launch this program again on the same computer. If you try to launch the DICOM Viewer again, the window of the launched program will be activated. If you try to launch the DICOM Viewer again with command line parameters, the parameters will be sent to the program that has already been launched (see Sections 20.1 and 20.2).
If the DICOM Viewer has already been launched and minimized to the system tray, the parameters will be sent to the current program regardless of the version and the edition chosen by the user (see Section 1.2).
If the program was launched on behalf of one user, it cannot be accessed by another user. In such a case, the current user has to shut down the program forcibly and then relaunch it. To do that, enable the Allow to close the application running as different users option in the program settings (see Section 16.3).
You can only launch another program version or edition after the currently running program is shut down.
Note that sometimes the program cannot exit immediately when the main window closes (e.g. if data is being transferred over the network, or if information is being written to a disk or flash card). In this case, if you try to launch the program, the main window of the launched instance does not open and you should wait until the launched instance exits and then launch the program again.
