Error 1612 - Can't Get Express Installed

I have done all I can to resolve this on my own and would really appreciate any help anyone can give me. I have run uninstall utilities, followed a few MSDN reinstall methods, but all roads lead back to this vicious cycle:

The install hangs trying to install the prereq Microsoft SQL Server 2005 Setup Support Files with Error 1612. So I try to uninstall the Support files using Add/Remove..but the Windows Installer looks for "Microsoft SQL Server Native Client" disk, which of course I don't have because I install from downloads from Microsoft.

That's the very short version. I've got a ton of hours reading help groups, MSDN, trying everything.

I have posted the error log file below. Thanks in advance.
