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

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 erwin Data Modeler, get an 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:

Any environment/OS related issues we will need to look at the log files for further investigations. However, some customers have tried the method below to resolve this issue.

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

Note:  erwin DM and Mart are created for Windows environment and have not been QA tested in Citrix environment.  However, some users are running erwin DM and Mart successfully on Citrix.  So while we can say generally it works, we do not officially support erwin DM and Mart on Citrix.
