SUMMARY
The message &quot;Unable to Establish Connection&quot; is returned immediately when trying to log on to the mainframe using Microsoft Excel's Data Access Macro (DAM) if the Data Access (CL/1) resources have not been installed.

To be sure that the resources have been installed, run the Installer again. If the Installer gives the following message, the CL/1 resources have been previously installed (click Cancel in this dialog box):

The resources you are attempting to add already exist on the destination file. Would you like to replace them?&quot; If no error is received, the resources were not previously installed. Attempts to log on to the mainframe should now be successful. If the error &quot;Unable to Establish Connection&quot; is received and the resources have been correctly installed, contact Microsoft Product Support Services at (425) 454-2030 for more information.
