Cannot execute command line within TS from batch

The folder structure of the package is this;

Notepad ++ 6.9 ENU

-> Sources
        -> notepad++.exe
-> Plugins
-> Images
        -> pic.jpg
-> Scripts
        -> install.bat

In my task sequence I am trying to run the install.bat file with the 'Run command line' step. My command is: cmd /c .\Scripts\install.bat

This is a simple problem I admit but I don't see it (yet) :-)
