Description: ODBC connection NOT working
Details:

Good morning.

I've been struggling with this install for most of a day now. Basically, the
program INSTALLS fine, but doesn't work. It's listed under installed
applications, but when you go to Admin/ODBC and check Drivers, there's no
listing for PostgreSQL. Because the driver's not showing, I can't create a
data source, which is necessary to access some important internal
applications.

I've looked around on the 'net for a solution, and the only one that looked
promising (installing PostgreSQL version 8.0) isn't possible since the
installer has been taken down. Any help would be appreciated!
