Run Command doesn't run internal commands

[TPGamesNL]

Okay so I have the issue that I want to open a new cmd window which will run a batch file with skUtilities, so I thought the command 'start cmd /c ' would do fine, but apparently every internal command (I tried a few) didn't work. Error: [skUtilities] v0.9.2: Can't run Command: 'start cmd /c <batch file>' - 'Cannot run program "start": CreateProcess error=2, Het systeem kan het opgegeven bestand niet vinden (EffRunCmd'.class) ('Het systeem kan het opgegeven bestand niet vinden' means 'The system couldn't find the specified file.') (List of internal commands)
