Windows XP Vertical mode Stand Alone game wont work

Im creating an interactive for a vertical (portrait) display in windows xp and every time I create a stand alone exe and display full it goes sideways. I've tried this in my PC with Windows 7 and it works fine.

But I cant get it to work in the kiosk. What can I do? And no changing to windows 7 is not an option they dont have the license and is going to be displayed on several computers.

Im Afraid to ask.. would I have to change the camera angle? I use several cameras in the display.

For those that may be curious, all you need to do to set portrait mode in PC is to go to display settings in windows and set the display mode to vertical. then just turn the monitor sideways, This is specially cool for pinball games and vertical shooters or to display newspaper like text.
