ArcGIS10:Using UML/CASE to Design Geodatabases with Visio2007-Add CASE Tools wizard

[ScottChang]

Hi all,
I managed to finish "Exporting a model to XMI" on Pages 43-45 of ESRI Tutorial "Designing Geodatabases With Visio".  I am going to do "Generating schema from an XMI" on Page 46 of the Tutorial: Adding the CASE Tools wizard to ArcCatalog. Step 1.  Once you install your Case Tools, right-click the Task bar and click Case tools.    I am completely lost in this Step.   Please kindly help and advise how I can get this Step started.
Thanks in advance,
Scott Chang

I struggled in understanding this Step for a while.  I searched my ArcCatalog 10 and found the "Customize" menu => Toolbars => CASE Tools => the Schema Wizard button !!!!! Then, I created a blank File Geodatabase "scFileGeoDB1-CaseTools-XMI-UML" in the folder of my CaseTools XMl Files created before, and following the instructions of "Connecting to an XMI file or repository" (on Page 47), "Selecting an XMI file" (on Page48), "Connecting to a repository" (on Page 49) and "Selecting an object model" (on Page 50). I executed the Steps on Pages 47 - 50, and I got an Error: Unable to create object class extension COM component [Building] - see the attached file for details that include Summary of Schema Wizard and Schema Wizard Log.txt.  This error is a real challenge to me and far above my head!!!!  Please kindly help and advise me how I can solve this problem.  I will be extremely appreciated, if you can help me in solving this error.
Thanks,
