Could not access system registry

Hi,
I am trying to insert the DS ActiveX window in 2007 PowerPoint, but every time I got the same error message as in the subject line. You have shown it works in 2003 PowerPoint.

I am using DS 2.0 in one computer, and just the Visualizer in other computers (all Windows XP). I tested at least 4 computers and none worked.

In 2007 PowerPoint I need to use the Developer Tab to get the visual tools, not like in 2003, but I only have 2007 version.

Thanks in advance.
