Digital Workshop

Hi everyone. I'm wondering if anyone has come acroos the same problem I am having with regard installing the IO web plugin. I create presentations for some clients who have them on the www and I upload them when changes are needed but that means installing the IO web plugin to each system using the publication - not a problem when i do it personally. But obviously I don't want them all knowing it is all written in Opus by sending them the .exe or .msi for the installation of the web pluging as it shows it is by DW. I need to keep this a secret from them. I remember a few years back the web pluging was install by right-clicking a .inf file and selecting Install. My question therefore is does anyone know the way to install the plugin into IE without executing the .exe or .msi so that I can get a couple of new clients displaying the presentations on the www without having to get a flight to Germany and do it myself. Thanks for any help guys and maybe slightly early but Happy Christmas to everyone on the forum. Regards Anthony
