Quickbooks Desktop Enterprize crashes for users on login

I have been working with QB data support and I am told the file and the data are good.  We are running the most current version of QB and have followed all the required set up by QB tech staff.  I have also set up another Windows Administrator to test and it fails the same way.

Issue:  When users try to log in, the application crashes.  Only the Admin can log in.

Note:

If the Admin logs into QB, logs out of the data file only, any user can log back into the application.  It is only when the application is completely closed, any user logging in crash the application with the exception of the Admin.
