infoRouter database connection fails at application startup.
This error occurs if you are pointing a to valid but older version of an inforouter database.
Check the IRWEB.DSN file located in the Application Path. (c:\inforouter\irweb.dsn). Open with a text editor such as notepad.
For MYSQL and MS SQLSERVER, make sure that the Database parameter points to a valid infoRouter database.
For ORACLE, make sure that the SERVER parameter points to a valid service for the infoRouter database.
