Thanks for the responses!

That's a good thought and one we were considering.  We do need to verify
the version of Office mainly because the interop msi will raise a message
to the users and fail if it is invoked on a machine w/o the proper version
of office.  That's easy to check though (this isn't final):

    <util:FileSearch Path="[ProgramFilesFolder]Common Files\microsoft
shared\OFFICE12\MSO.dll" Result="exists" Variable="Office12Installed"/>
    <util:FileSearch Path="[ProgramFilesFolder]Common Files\microsoft
shared\OFFICE14\MSO.dll" Result="exists" Variable="Office14Installed"/>
    <util:FileSearch Path="[ProgramFiles64Folder]Common Files\microsoft
shared\OFFICE12\MSO.dll" Result="exists" Variable="Office12Installed64"/>
    <util:FileSearch Path="[ProgramFiles64Folder]Common Files\microsoft
shared\OFFICE14\MSO.dll" Result="exists" Variable="Office14Installed64"/>

 then

<MsiPackage Name="Prerequisites\o2007pia.msi"
SourceFile="$(var.Prerequisites)Office2007PIARedist\o2007pia.msi"
DisplayInternalUI="yes" Permanent="yes" Visible="yes"
InstallCondition="Office12Installed OR Office12Installed64" />

Just a thought but if you need them why not just install them it doesn't
matter if they are already there and the GAC handles its own reference
counting so removing your application wouldn't remove them if another
application had installed them.

Subject: [WiX-users] Burn: Search GAC



>From my Bundle, I need to determine if the Microsoft Office Interop

assemblies are installed on the machine.  I think the only way to do this
is to search the gac for the assemblies.  This is because the assemblies
can be installed by various different packages and there may not be a
product install for them on the machine, even if they are there.



Ideally, I'd like to be able to search a directory tree from a root
location, e.g. "[WindowsFolder]Assembly", with a wildcard
"Microsoft.Office.Interop.*.dll" and have it tell me if files were found.

-- I do understand that his may not be quite possible right now.



Under the Product element when authoring Wix installers, the DirectorySeach
element as a "Depth" attribute.



Under Bundle, BAUtil's DirectorySearch does not have this attribute, so I'm
at a loss on how to search the tree under a directory.



How can this be accomplished under Bundle?



Thanks!
