Hi David,

With regards to the above error, you may receive the error when SQL Server service was not installed correctly or the SQLBrowser service is not running and is disabled. Can you tell us which version of SQL Server you are using? Whether you are using a SQL Express Free Edition or SQL Standard, Workgroup or Enterprise?

Vienna can reconfigure the database connection settings, if you delete the config.ini file from "My Documents\NMQA\Vienna Files\Configuration\" directory and start Vienna, the database configuration screen will appear allowing you to choose the SQL Server to use. After Vienna detects the SQL Servers installed on the local machine, the result should look like: "MachineName\SQLExpress" on the drop down list.

If this does not resolve the issue, you can install another named instance of SQL Server by downloading the setup file from http://www.microsoft.com/downloads/de.... Make sure to uncheck the "Hide advanced configuration options" and when asked for the instance name, you can type in "ViennaInstance".

Kind Regards,

NMQA Support
