Have you already installed PostgreSQL once before? If so you may receive this error message; PostgreSQL only needs to be installed once.
Are you on an account with Administrator privileges? You need to be in order to be able to install PostgreSQL properly. Please make sure your account has these rights.
This can also happen as a result of certain anti-virus software being particularly unpleasant. F-secure apparently does this, I'm not sure about any others off the top of my head . . .
