There is no way to install "PostgreSQL 8.0.0 Beta4" and any other version in my windows 2000. No matter what user i use or any kind of configuration option combination it's allways the same.
This is the wrong list for reporting installer bugs. You should probably try contacting windows-installer team as it's not part of the core PostgreSQL database anyway.

They have bug trackers and mailing lists available. It's worth checking the mailing list archives to see if anyone else has similar problems.
Also check the FAQ:
http://pginstaller.projects.postgresql.org/FAQ_windows.html
It notes that firewall/antivirus programs can cause problems - check your logs.
For what it's worth, I've not seen reports like yours before, so there could be something different about your Windows 2000 machine versus most people's.
