Silent Mode not launching

I'm trying to run the ccleaner setup from a batch file in silent mode using the /S switch, but it doesn't do anything. Is there something I'm missing, or is this feature removed from the new version of Ccleaner?

Thanks

Here's how to make CCleaner automatically run and close itself:

ccleaner.exe /AUTO

Should look like this (use the quotes):

"C:\Program Files\CCleaner\ccleaner.exe" /AUTO

or like this:

"%ProgramFiles%\CCleaner\ccleaner.exe" /AUTO
