You'll be wanting to take your question to the (official) HP Forums, http://forums.itrc.hp.com/cm/ - this is a _calculator_ forum, not a printer one. And there aren't any HP calculators that run Powerpoint, so you're presumably getting your error from Windows, and forums.itrc is still the better place.
