Description:

When trying to open ERwin, the toolbar, such as the Font & Color Toolbar, first displays at the top of the screen and then ERwin crashes.   Why and how to fix that?

Solution:

That is due to the toolbar coordinates somehow becoming compromised and then ERwin could not open using those coordinates. 

Renaming the folder to OLD in the registry here,
           
HKEY_CURRENT_USER\Software\CA\ERwin Data Modeler\7.3
                         
will force the creation of a new folder with the original name using the default coordinates.

WARNING:  first open your registry editor and make a backup of the complete registry.  Go to the top most item and select to export there.  That way if anything goes wrong you can recover.
