Hello, I am attempting to install PostgreSQL. I downloaded 8.2.12-1zip from ftp9.us.postgresql.org and then followed the installation instructions outlined in http://pginstaller.projects.postgresql.org. I am installing on a Windows XP machine with an NTFS file system. I opened the zip contents from a temporary folder with all internet security functions disabled. When I reached step 11 in the instructions, I received an error message: "Internal account look-up failure. No mapping between account names and security ID was done." I retried several times using a new download from a different mirror, but always received the same error message. I searched for and found a prior reference to this message (Sept 04 2008) but ws unable to retrieve the full message and response. Can you offer any suggestions for dealing with this problem?
