I'd suggest that you ask this in the InDesign forum appropriate to
your platform (Windows or Macintosh).
if you're accessing the Adobe forums via the web,
http://www.adobeforums.com/cgi-bin/webx/.3bbf275c/
or
if you're accessing it through a news reader
adobe.indesign.macintosh
or
adobe.indesign.windows
You could also contact Adobe product support directly, particularly
since this is an installation issue.
