I have suddenly lost the ability to insert Shockwave or Flash content into my
PowerPoint presentations. This problem began after our computers were
upgraded to Flash 9 and Shockwave 10 and may also be connected with a problem
I had with a corrupted presentation containing Flash content.

When I open a presentation with an embedded SWF or DCR, I get "Some controls
on this presentation can't be activated. They might not be registered on this
computer." If I try to add new content, SWFs added as a "Shockwave Flash
Object" appear to work (no error messages) but don't play. Attempting to
insert a "Shockwave ActiveX Control" gives the message "Object library
invalid or contains references to object definitions that could not be found."

I have uninstalled and reinstalled both Flash and Shockwave and verified
that they work in both Firefox and IE. PowerPoint, however, doesn't seem to
be getting the message.

Any suggestions?
