I am trying to install the software and have only gotten to the Database Control Panel and it says I need to download "postgresql-8.3.msi to begin the installation". When I go through the process to get this I only have the option of opening (postgresql-8.3 or postgresql-8.3-int). I try to open the first one and it ask what language and I click English and then after a few seconds I get this "This installation package could not be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid windows installer package.)
I am stuck at this point and need help to get this installed.
