Preventing "Parallels Internet Security" dialog

Hi all,
Anyone know how I can prevent the dialog for "Parallels Internet Security" from popping up for all users on a network? Currently when any user logs on they get the dialog to install PIS. Clicking don't show again only works for the person currently logged in.
I work at a school and don't want students to be able to install PIS at all. Our network is geared to McAfee, with automatic updates on login, so this persistent dialog is a pain.

 

Me too also has this annoying pop up dialog problem!!!

Please anyone tell me how to disable it!

I do not like it!

Thanks!

 

Anyone any solution, please!
