Updating CCleaner

Hi Guys,

I am currently writing a script that will auto run CCleaner - as well as Malwarebytes & Spybot, and probably others in future.

Is it possible to update CCleaner through cmd? I have looked at the online helpfile (http://docs.piriform.com/ccleaner/advanced-usage/command-line-parameters) but cannot find this?

All help is much appreciated,

andy
