We need to apply Studio updates as Silent Installation. At the end of each installation, Studio needs to be opened as admin to unpack all plug-ins in C:\ProgramData\SDL\SDL Trados Studio\14\Plugins\Packages. In case there are unsigned plug-ins, a dialog box is displayed and the admin needs to confirm. However, during Silent Installation, displaying dialogs is not possible. Therefore, it needs to be possible to confirm all unsigned plug-ins via command line argument.
