I'm unable to run the Pack and Go Wizard.
The PowerPoint Viewer would not open my presentation.
The Microsoft PowerPoint Viewer will not run password-protected presentations, nor can you package the viewer (in the Pack and Go Wizard) with a presentation that's password-protected. If you need to show a password-protected presentation, you need to show it in PowerPoint. If you must show it by using the viewer, save it without using a password.
