For this game it is easier to use this
Code:
xcopy /e /i /y /q "{src}\game" "{app}" >nul 2>&1
It will copy the whole folder + subfolders and all it's file to {app} folder.
No need for destination file name.
Source folder ({src}) is simply from where you install it. It has nothing to do with CIU folder. It's the same if you would like to install redist from disc.
