Hi Kevin, I have checked this several times. The installer is executed by user Administrator (which apparently has all Administrator privileges) The user postgres is also being created and the data directory is owned by this user, which does have read, write, execute, modify, list folder contents and they are all inheritable. Here I am copying few more lines from the logs, upto when initdb failed. " Ensuring we can write to the data directory (using cacls): processed dir: C:\PROGRA~1\CISCOS~1\CSCONccm\objects\PostgreSQL\8.4\data The files belonging to this database system will be owned by user "Administrator". This user must also own the server process. The database cluster will be initialized with locale English_United States.1252.
