Not able to install PostgreSQL on WIndows using and administrative user

Good day,

I am attempting to install 8.2.3 on Windows. I cannot install using my
DOMAIN user or a local user that are part of the local ADMINISTRATORS
group. I can install if I specify a local user that is not part of an
administrative group.

If I use an "admin" user, I see these errors:

1. A pop-up saying I do not have privileges to continue the
install. This occurs at the point of the installer where it is granting
permissions on the new files.
2. The pgerrm.log file has:

processed dir: C:\PostgreSQL\8.2

Access is denied.

3. The postgresql-8.2.log has (at the tail end):

=== Logging stopped: 2/12/2007 15:44:54 ===

MSI (c) (F8:A8) [15:44:54:455]: Note: 1: 1708

MSI (c) (F8:A8) [15:44:54:455]: Product: PostgreSQL 8.2 -- Installation
failed.

I found that if this local user was granted admin rights (part of an
admin group) the same errors occur. My domain login also has admin
privileges on this machine.

According to the Windows Install FAQ at
http://www.postgresql.org/docs/faqs.FAQ_windows.html#2.3, I should be
able to use an administrative user.

"2.3) Why do I need a non-administrator account to run PostgreSQL under?

...

Note, that with the release of PostgreSQL 8.2, it is possible to run
under a administrative account. PostgreSQL 8.2 and above are able to
irrevocably give up administrative rights at startup thus ensuring the
rest of the system remains secure in the extremely unlikely event that
PostgreSQL becomes compromised."

Thanks,

Michael
