Install fails on Vista Home Premium 64 bit

I've downloaded and ran ejabberd-2.0.4-windows-installer.exe. I then get this message:

   Error running Post Install Script.
   The installation may have not completed correctly.

I've tried running C:\Program Files (x86)\ejabberd-2.0.4\bin\postinstall.cmd as an administrator and I get this error:

Windows Script Host
Script: C:\Program Files (x86)\ejabberd-2.0.4\bin\manual.vbs
Line: 10
Char: 1
Error: Invalid root in registry key "HKLM\SOFTWARE\Ericsson\Erlang\ErlSrv\1.1\ejabberd\InternalServiceName".
Code: 80070002
Source: WshShell.RegRead

I do not have the registry key: HKLM\SOFTWARE\Ericsson

So I tried install erlang: http://erlang.org/download/otp_win32_R13A.exe, It installed successfully but I still don't have that registry key.

If I try running ejabberd anyways with C:\Program Files (x86)\ejabberd-2.0.4\bin\start.cmd
It says Starting ejabberd... for a while then opens an error page in my browser with a link to a log, The log contains this:

                          {win32_dns,pick_config,0}]}}}}
    type: temporary

That looks like a dns issue, my dns is working fine. I've tried different things from the ejabberd server domain in the installation, such as my machine name, localhost, 127.0.0.1, etc.

Any ideas on where to go from here?
