Template General Purpose does not exist. Please specify an existing template for database creation.
It assumes the template file name is provided, not the template display name. Simply modify the response file you have.
e.g.
From
TEMPLATENAME = "General Purpose"
To
TEMPLATENAME = "General_Purpose.dbc"
Re-run your installation and it should be fine now.
