Here is little sample on updating value of the attribute in App.config:
App.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="Key1" value=""/>
</appSettings>
</configuration>
Wix code:
<!-- Set value of Key1 -->
<XmlConfig Id="SetKey1"
Action="create"
Node="value"
ElementPath="//appSettings/[EMAIL PROTECTED]'Key1'[\]]"
VerifyPath="//appSettings/[EMAIL PROTECTED]'Key1'[\]]"
Name="value"
Value="[INSTALLLOCATION]"
File="[#AppConfig]"
On="install"
Sequence="1" />
Hope this helps,
Alex Shevchuk

Subject: [WiX-users] XmlConfig question
I have a question about the XmlConfig custom action. My application is a
.NET application, and is deployed with an application.exe.config file.
Based on properties gathered during the installation, I want to update
the values in the config file. Here's the relevant portion of my config
file.
<configuration>
<databaseSettings server="" databaseName="" userName="" password="" />
</configuration>
The only way I can get XmlConfig to work is to delete the
<databaseSettings /> element and re-add it, then add the attributes to
the recreated element. Do I have to do it this way, or is there some
syntactic magic I don't yet know to get XmlConfig to write the
attributes directly?
N.B., I'm using a custom configuration handler in my application to read
and write these elements so it is correct that the do not exist as a
child of appSettings, and no, I'm not storing the password in plain
text.
