Another Yahoo toolbar topic. Please advise

 Pure and simple I do not want the Yahoo toolbar when installing the product. I am pushing pdf creator out to mutiple users using the following command

"PDFCreator-1_2_3_setup.exe" /verysilent /components=\\"!toolbar\\" /tasks=\\"!desktop_icon\\" /f

When I install the product all is fine however when I launch PDF creator to print a pdf then I look in Add/Remove programs and the toolbar is installed. It's as if it's activating it on first use.

How do I stop this feature from installing, it is not required. 

 Apologies. It is installing the toolbar regardless.
