If you want to save the illustration from Creo Illustrate with a lot of figures (include animation), then you can only make the export in PVZ format (in main menu go to: "File" -> "Publish" -> "Publish"). Then you can view your PVZ file in Creo View Standart (or Creo View Express). And if you want it to view your file in an HTML page you need to use Creo View Toolkits package (some more information can be found here: http://communities.ptc.com/groups/technical-illustration/blog/2012/03/29/what-s-new-in-creo-illustrate-20-part-46).
