Failed to open model viewer error, for Decision Tree Model

I am trying to follow ODM tutorial here :

http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/11g/r2/prod/bidw/datamining/ODM11gR2.htm

After completing initial analysis, I want to investigate the Decision Tree model more closely. As I choose View Models > CLAS_DT_1_1, I get an error message:

Failed to open model viewer

Details are:

I get this error for Decision Tree Model only. For other models, there is no problem. How can I fix it?

Thank you.
