I have tried to install postgreSQL on my WINDOWS 7 but it just does not seems to work.

When installing, it stuck at "starting services". It says, "Service 'PostgreSQL Database Server 8.0.0-rc1' (pgsql-8.0.0-rc1) failed to start. Verify that you have sufficient privilleges to start system services."

I have tried the solutions for Installing PostgreSQL 8.1 on VISTA from this forum but still nothing goes...
