Error when trying to use WSF TypeLib reference to "WindowsInstaller.Installer"? Help!

[news.microsoft.com]

[This is really a WSH question as much as an MSI question, which is why I'm
cross-posting.]

I have a number of VBscripts which are organised under an WSF file and run
by the Windows Scripting Host. The VBScript use the Windows Installer COM
API.

I'd like to add a reference to the "WindowsInstaller.Installer" object so
that I can use the constants defined in the MSI TypeLib. I've done this for
other object models before, but not MSI.

Anyway, when I attempt to add a reference either using the ProgID or GUID

<reference id="Microsoft Windows Installer Object Library"
object="WindowsInstaller.Installer"/>
OR:
<reference id="Microsoft Windows Installer Object Library 1.0"
guid="{000C1092-0000-0000-C000-000000000046}"/>

I get this error when I call the script using CScript.exe:

MSILibrary.wsf(0, 1) Win
Cannot add reference : {000C1092-0000-0000-C000-000000000046}

I'm on Windows XP. Does anybody have any ideas?

Not sure how you have setup things. But putting the following in a wsf file
will work(at least on my Win2K machine)

<package>
<job id="Job1">
<reference object="WindowsInstaller.Installer"/>
<script language="VBScript">
'this should return 4
msgbox "msiViewModifyReplace=" & msiViewModifyReplace
</script>
</job>
</package>

Unfortunately, your simple example generates the same error ("cannot add
reference {GUID}") on this computer as I had with my more complicated
example.

It's a WinXP computer, and I can install software so I know the installer
service is working; I can also createobject ("WindowsInstaller.Installer")
so I know MSI.DLL is registered and late-binding is working.

I have no idea what could be causing this problem. Maybe it's an
early-binding issue; something to do with the script engine attempting to
get a reference to the TypeLib?

Very strange. I've solved it by declaring the Windows Installer constants in
a common.vbs which is included with every .vbs job in a package;

*HOWEVER* I'd still like to know what is causing the error because I'd like
to use <reference> instead.

??? Kallely's example also works OK for me on W2K Pro sp3...

Same thing for me on XPSP1; works fine.

<package>
<job id="Job1">
<reference object="WindowsInstaller.Installer"/>
<script language="VBScript"><![CDATA[
'this should return 4
msgbox "msiViewModifyReplace=" & msiViewModifyReplace
]]></script>
</job>
</package>
