Re: [WiX-users] Conditionally edit XML file if it is installed

[Pierson L. (Volt) <a-...@mi...>]

Would it be worthwhile to do a filesearch and if it doesn't exist to then i=
nstall the component and change the file (in a different feature)?

That would be the way I'd do it, but I have yet to use the NeverOverwrite o=
ption.

Subject: [WiX-users] Conditionally edit XML file if it is installed


I am trying to have my installer edit an XML file after it is installed.
However, the XML file should not be installed or edited if it already
exists on the system.  So I am trying to condition the installation of
the XML editing component on the state/action of the component which
contains the XML file to be edited.  But its not working.

I am seeing some conflicting info in the Windows Installer documentation
that in one place states the component state can only be used in the
condition table and the sequence tables, while the Component table
documentation states that the Condition column "accepts conditional
expressions containing references to the installed states of features
and components...".

So which is it?
Any idea what I'm doing wrong?
