When opening any model in a Citrix environment, get error "GDM Exception thrown at % 1. " or a Visual C++ crash error - why?

Error Message:

ERwin:  Visual C++ crash error

Mart (WE): GDM Exception thrown at % 1

 Description:

When attempting to open any model in a Citrix environment, whether from the Mart or locally from CA ERwin Data Modeler, get the error.  The Mart error is "GDM Exception thrown at % 1. " or locally, it is a Visual C++ crash error.   When opening the same model (locally) from the Windows 7 machine, no Citrix connectivity, model opens without any error.  What could be the reason?

Solution:

User's Citrix team determined that user profile somehow was corrupted.  Deleting the Critrix profile and recreating it resolved the Mart open error and CA ERwin models open without Visual C++ crash error.
