You likely don't need your own CA for this, check out XmlConfig or XmlFile.
Your problem here is likely that you get a FileNotFoundException or something
similar which is due to the fact you have your CA scheduled to execute in the
"immediate" sequence and scheduled after "InstallFiles" which doesn't put any
files onto the machine until the "deferred" sequence.

Subject: [WiX-users] C# Custom Action, change some files during installation
Hi!
I'm struggling with this for some time now... I'm trying to make my custom
action to modify applications config.exe file but no success. Maybe someone
can help??
<CustomAction
Id="EditConfig"
BinaryKey="EditConfigDLL"
DllEntry="EditCPConfig"
Execute="immediate"
Return="ignore" />
<Binary Id="EditConfigDLL" SourceFile="ConfigEditCA.CA.dll" />
<InstallExecuteSequence>
<Custom Action="EditConfig" After="InstallFiles" Overridable="no"></Custom>
</InstallExecuteSequence>
And here is c# code:
public static ActionResult EditCPAConfig(Session session)
{
string db_user = session["DB_USER"];
string db_password = session["DB_PASSWORD"];
string u_profile = "localSU";
string installdir = session["INSTALLDIR"];
System.Xml.XmlDocument xml_doc = new System.Xml.XmlDocument();
System.Diagnostics.Debugger.Launch();
xml_doc.Load(installdir + "Cairo.Producer.Admin.exe.config");
System.Diagnostics.Debugger.Launch();
System.Xml.XmlElement conf_elem = xml_doc.DocumentElement;
System.Xml.XmlElement conn_string =
(System.Xml.XmlElement)conf_elem.FirstChild;
System.Xml.XmlElement add_conn = xml_doc.CreateElement("add");
add_conn.SetAttribute("name", u_profile);
add_conn.SetAttribute("connectionString", "something");
add_conn.SetAttribute("providerName", "Npgsql");
conn_string.AppendChild(add_conn);
xml_doc.Save(installdir + "Cairo.Producer.exe.config");
System.Diagnostics.Debugger.Launch();
return ActionResult.Success;
}
Code works when i put files in installfolder on my computer...
