open office portable on CD - Register screen

Hi,

I have install Open Office Portable on my drive, and executed it, then copie the ini file.
It work fine on my local drive.

But when I copy the file on the CD, Open Office show me the welcome screen for registration.
How can I bypass the option.

The objective is to have on a CD, open office which will start automatically a presentation opd.

Any Solution ?
Or I am looking for a small aplication which will be able to open a presentation OOO *.opd) like the Microsoft Version of PPTViewer.

Thanks.
