On Windows XP you may find that ClaroRead does not play in Adobe Reader with highlighting. Disabling Protected Mode may fix this.

  • Opening Adobe Reader, open the Edit menu, and select the Preferences menu item.
  • From the Categories list at the left select “Security (Enhanced)”
  • Uncheck “Enable Protected Mode at startup” at the top.
  • Restart Adobe Reader and try reading with ClaroRead again.

(The setting is located at the bottom of the General tab on older pre-XI versions of Adobe Reader)
