No, you have to install the drivers which apply to your specific Powerlite model. Drivers (XP & Vista) for the 9100EP are here:

Note: Windows 7 is not officially supported on the 9100EP as there are no Windows 7 drivers for it. You'll have to try the Vista drivers, some of them may work, others may not. That's the best I can do.
Don't bother trying XP drivers as they definitely won't work on Windows 7.
