Hi Ray, Have you got any luck to get around this issue? I am having the same issue. I just installed PostgreSQL 9.1 with Stack Builder 3.0.0. Every time I was trying to install additional software I received the error message popped out saying ...http://www.postgresql.org/application-v2.xml cannot be opened. http://postgresql.1045698.n5.nabble.com/file/n4986851/postgreSQL.jpg I am with a home computer running Vista and not within an LAN. I am able to display the XML file in the browser. Could anybody please help out? Thanks, Cheers, Alex -- View this message in context: http://postgresql.1045698.n5.nabble.com/Help-with-Stack-Builder-tp3262069p4986851.html Sent from the PostgreSQL - general mailing list archive at Nabble.com. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
