How to embed Spi-V in a Powerpoint Presentation?

Since I don't own Powerpoint myself (really...), I am going to quote freely from this article at Microsoft which deals about Flash instead of Shockwave. Paraphrasing that document (note that this will only work on windows):

1. First make sure SPi-V and your document work in Internet Explorer
2. In normal view in PowerPoint, display the slide on which you want to play the panorama.
3. On the View menu, point to Toolbars, and then click Control Toolbox.
4. In the Control Toolbox, click More Controls (the button with the hammer and wrench icon).
5. In the list, scroll down and click Shockwave ActiveX Control, then drag on the slide to draw the control. You can resize the control at any point by dragging the sizing handles if you need to adjust it to the size of the animation.
6. Right-click the Shockwave object, and then click Properties.
7. On the Alphabetic tab, click the Movie property.
8. In the value column (the blank cell next to Movie), type the path URL of the SPi-V engine file (SPi-V dcr).
9. Next, set at least these options:
   • swURL -> the relative url of what you want to display to the SPi-V.dcr file
   • swStretchStyle -> stage
   • bgColor -> #000000 (optional, to the color you want)

In OpenOffice Impress, here's what you do (and this should be cross platform)

1. First make sure SPi-V and your document work in a netscape-like browser (ie: not internet explorer)
2. In normal view in Impress, display the slide on which you want to play the panorama.
3. From the Insert menu, choose Object -> Plugin
4. Fill in the URL to, or browse to the SPi-V.dcr file
   If you browse for the file, be sure to select 'Shockwave for Director' as the file type.

5. In the Options textbox, specify these options:
   

   swurl="pathToYourPanorama.xml"
   swStretchStyle="stage"

Hi,

after I tested their Tutorial for SPiV in PowerPoint unfortunately appears to run at the Power Point presentation every time following error message:

"This application requires an Xtra (Flash Movie...) that either does not exist or failed to initialize properly. Please make sure the appropriate Xtras are in the Xtras folder(s)."

The specified Xtras folder, but is ready and contains all the necessary Xtras (16 files). So the SPi-V.dcr file and Pano are in a folder and a layer below the Xtras folder.

Does this file have to be indicated in the PowerPoint characteristics somehow as or does need I still additional Xtras for PowerPoint???

Thanks for the help.
Best Regards,
