Issue with creating PowerPoint slides

["Data Analytics Corp." <dataanalytics@earthlink.net>]

Hi,

I just got a new laptop with Vista and Office 2007.   I loaded S+ 8.0 on 
this new machine and proceeded to work on a project creating multiple 
graphs tabs which I wanted to convert to PowerPoint slides. When I ran 
S+8.0 on Windows XP using Office 2000 on my old machine, I used the 
PowerPoint dialog box to create PowerPoint slides all at once from 
multiple graph tabs.  Now on my new machine, I get an error message:
       RUN-TIME error '6303':
       The PROGID S-Plus.GraphSheet cannot be converted to a valid CLSID.

Ok - what does this mean and how do I fix it so I can do what I use to do?

Thanks,
