Problem:

When opening the Admin module an error “Database could not be opened” appears

Cause:

Incorrect setup or access to the database

Resolution:

Ensure you have you created the System DSN using the 32bit version of the ODBC?

Ensure that the DSN name as well as the SQL db are named exactly the same in both application?

Also check that in SQL user used on ODBC has full access to the Retail database.
