Description

If you want to allow the execution of batch files within the SiteKiosk user account you have to allow the execution of the program cmd.exe by using the System-Security-Manager (-->Customized-->Programs).

Furthermore you have to allow the display of the command line window by configuring the Windows & Dialog Management of SiteKiosk (SiteKiosk configuration "-->Access/Security-->Block system critical windows & dialog boxes-->Settings" >>delete the entry "ConsoleWindowClass," from the list).
Alternatively add the title of the dialog window to the list to allow only this window explicitly.

Please note that deleting the entry from the "Windows & Dialogs" list and allowing the execution of the cmd.exe file presents a potential security risk.
