Microsoft PowerPoint supports QuickTime including QTVR on both Windows and MacOs platforms. The support for QuickTime is more robust and much more straight forward on the Mac version of PowerPoint. PowerPoint for Windows does not directly support QTVR, but can be made to do so by two means.

MacOS - Consult the PowerPoint documentation on embedding QuickTime in your pages.

Windows - You can embed your QTVR movie in an html page, then embed the html page in your PowerPoint page. PowerPoint will use Internet Explorer to display the html and the QTVR will work

ActiveX Control - An ActiveX control of QuickTime is now available which allows PowerPointfor Windows to play all kinds of QuickTime including QTVR. You can get a free "unregistered" version from QT4Delphi. I have not tried this, but have heard it works well.
