I thought the original request was to open a password protected file.
If the user wishes to protect the contents from editing, converting the
PowerPoint presentation to an Adobe PDF file format work well for this
purpose with the added benefit of being readable on all platforms across
multiple operating systems and multiple generations of acrobat. Many
mobile
devices allow the file to be viewed, too.
One would think that Microsoft would at least provide a viewer for
PowerPoint DRM protected files that works on non-Windows operating
systems.
