Argent Advanced Technology 3.1A-1404-A or earlier


Tuesday, 17 June 2014


If Argent AT Main Engine uses SQL Mirroring of SQL Server 2008 or later, when customer tries to install Argent AT client, he gets DB connection error message

When client setup program tries to use the old ODBC Driver, DB connection error shows up
