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?
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.
