Hmm, after further inspection on XP i've found there was another problem, which
was fixed by requiring administrative rights.
When running from a LUA account:
- On XP it now gives a message that an administrative user should run the
installation.
- On Vista, however, this message does not occour, nor a UAC is prompted; it
just happely starts installing... (although the condition requiring
administrative access should fail?)
Which still leaves the odd thing that installation on Vista elevates as
required and XP doesn't seems to do that?
And on Vista it still seems that the XML COM server doesn't seem to run
elevated and therefor cannot edit the XML file.
Did you read the MSDN link on COM Elevation Moniker? (
http://msdn2.microsoft.com/en-us/library/ms679687.aspx )
There is a part that mentioned: HKLM\Software\Classes\CLSID
{CLSID}\Elevation\Enabled = 1 Maybe this is something?
I also found some info on why not use ::CoCreateInstance() on
http://weblogs.asp.net/kennykerr/archive/2006/09/29/Windows-Vista-for-Developers-_1320_-Part-4-_1320_-User-Account-Control.aspx
But as i think you guys at Microsoft should know all this better than me? ;)

We don't ACL any files. The XML file is just installed by the MSI installer in
elevated mode.
The user running the installer has least user access (LUA).
It is possible to log in what user state runs the COM InProc server, i doubt
the COM is indeed called in any elevated state..
The mentioned problem also exists on XP with a very restricted user, so it is
not just a Vista problem, but we've found it first in Vista so we thought it
was a problem in/with Vista.
Can you checked the issue yourself?
I am willing to try and change some things in the WiX sources; just to see i'm
right ;) But it seems a bit of task to get the WiX sources compiling.. (At
least at this moment)

The ExecXmlFile is already running in an elevated process so the elevation
moniker should be unnecessary. Besides, the fact that you're failing when
running as a local administrator means that UAC is not the issue. It looks
like the problem is somehow related to the file only being accessible by the
domain administrator. Did you ACL the file down such that only the domain
admin can access it?

Hi,
I posted this though to wix-dev since i believe the problem lies in WiX.
When looking at the source coude i found that XmlFile is useing the MSXML COM
object.
This is done by calling ::CoCreateInstance().
When looking into ::CoCreateInstance() and COM and Elevation i found that you
should use a Elevation Moniker.
Check at MSDN: http://msdn2.microsoft.com/en-us/library/ms679687.aspx
I also found that more ::CoCreateInstance() calls might be affected due to the
missing elevation.
Can you guys at the Dev team look at this asap since it it is really a stopper
for me! (I think Bob is the guy for this ;) )
As said, i am using WiX 2.0.5213.0. I think is worth a new release for WiX 2.0
??

Albert van Peppen

Onderwerp: [WiX-users] Failed to open XML file on Vista
Hi,
I try to install a XML file through my WiX Installer.
On WinXP i have no problems.
On Windows Vista (Business Edition), client in a Win2003 AD network, i have
some strange problems;
- Installing as a domain administrator gives no problems.
- Installing as a local administrator gives an error; installation fails.
- Installing as a local or domain user with restricted rights gives an error;
installation fails.
- Installing with elevated rights / run as gives an error; installation fails.
(With the exception of Run As domain Administrator)
In all cases where the installation fails the following error appears:
'Failed to open XML file WInsad.xml, system error: -2147024786'
The logfile shows:
MSI (s) (18:E0) [12:50:19:270]: Running as a service.

Actie beëindigd 12:52:31: InstallExecute. Retourwaarde 3.
The following piece of code is what i use in WiX:
<!-- ===== WInsad.xml = License file ===== -->
<DirectoryRef Id="INSTALLDIR">
<Component Id="WInsad.dat" Guid="xxxxxxxx-xxxx-xxx-xxx-xxxxxxxxxxx">
<File Id="File_WInsad.dat" Name="WInsad.dat" DiskId="1"
Source="$(var.MyApplicationSourcePath)\WInsad.dat" Vital="yes" />
</Component>
<Component Id="WInsad.xml" Guid="xxxxxxxx-xxxx-xxx-xxx-xxxxxxxxxxy">
<File Id="File_WInsad.xml" Name="WInsad.xml" DiskId="1"
Source="$(var.DrumisApplicationSourcePath)\WInsad.xml" Vital="yes" />
<XmlFile Sequence="10" Id="Winsad.xml_License"
File="[INSTALLDIR]WInsad.xml" Action="createElement" Name="License"
ElementPath="//WInsad" />
<XmlFile Sequence="11" Id="Winsad.xml_LicenseType"
File="[INSTALLDIR]WInsad.xml" Action='setValue' Name='type' Value='Demo'
ElementPath='//WInsad/License' />
</Component>
</DirectoryRef>
<!-- Features -->
<FeatureRef Id="MainFeature">
<ComponentRef Id="WInsad.dat" />
<ComponentRef Id="WInsad.xml" />
</FeatureRef>
The initial WInsad.xml file is installed on the targetsystem before the error.
It initially looks like:
<?xml version="1.0" encoding="windows-1252"?>
<WInsad>
</WInsad>
The WiX version used in Wix-2.0.5213.0
Am i doing something wrong or is it something with Wix-2 / Vista?
The InstallerVersion in the Package is set to "200", the InstallerPrivileges is
set to "elevated".
Any help is welcome.

Albert van Peppen
