SQL Server 2005 Installation Failure On Vista

Help! I'm trying to install SQL Server 2005 on 32-bit Vista RTM. Have tried several editions (Developer, Standard, Enterprise). Have tried installing while logged in as domain user account in machine administrator group as well as built-in Administrator user. Running SETUP program with elevated privilges. Certain portions (Analysis services, Notification services) install correctly, but never the database engine. Always fails consistently with the same error reported. Machine has Visual Studio 2005 installed already, but NOT SQL Server 2005 Express Edition. Error logs reports are below ({computer name} is the name of my machine)

UI error reported:
