I've done a search but I cannot find a solution...

Is there a command line option/parameter to avoid the "Update existing portable installation" (or words to that effect) dialogue when updating an existing Calibre Portable installation?

I'm trying to set up a silient update process and that is the only thing stopping it at the moment. I have the installation directory sorted as per the Calibre Portable download page.

Thanks in advance.
