Prior to version 2.16.7.0 of Vision, the application required that they are also users of Aeros ERP. With this release, this is no longer a requirement.
In 2.16.6.0 and older, the AerosVisionConnections.XML file has to point to the ERP database. Then, within the ImportExportConnections table, there was a record (Type=5) that provided the connection string to the Vision database.
For 2.16.7.0+, this is no longer required.
