Wix Custom Action Implementation for Writing Installfolder in text

Question

I have following Wix Code that is supposed to send the value of property to Custom Action Written in C#. Basically what I want is when the MSI is installed, I want to write the path of Folder where Wix installed the program in text file. I referred to this site and created code accordingly, but my Custom Action isn't working.

Following is my Wix File:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Product Id="*" Name="SetupInstallFolder" Language="1033" Version="1.0.0.0" Manufacturer="LP" UpgradeCode="9e10a7d8-4ffb-493c-8318-c44ba4bc0c4c">
        <Package InstallerVersion="200" Compressed="no" InstallScope="perMachine" />

        <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
        <MediaTemplate />

        <Feature Id="ProductFeature" Title="SetupInstallFolder" Level="1">
            <ComponentGroupRef Id="ProductComponents" />
        </Feature>
    </Product>

    <Fragment>
        <Directory Id="TARGETDIR" Name="SourceDir">
            <Directory Id="ProgramFilesFolder">
                <Directory Id="INSTALLFOLDER" Name="SetupInstallFolder" />
            </Directory>
        </Directory>
    </Fragment>

    <Fragment>
        <ComponentGroup Id="ProductComponents" Directory="INSTALLFOLDER">
      <Component Id="SomeRandomEXE">
        <File Source ="G:\SarVaGYa\myworkspace\LatestLpa\lpa\lpa_c\here\src\lpa\Release\lpa.exe" />
      </Component>      
        </ComponentGroup>
    <Binary Id="SetupCA2"  src="G:\visual studio stuffs\SetupCAInstallFolder\SetupCAInstallFolder\bin\Release\SetupCAInstallFolder.CA.dll"/>
    <CustomAction Id="INSTALLFOLDERFINDER" Execute="immediate" Property="INSTALLEDPATH" Value="[INSTALLFOLDER]" />
    <InstallExecuteSequence>
      <Custom Action="INSTALLFOLDERFINDER" Sequence="2"></Custom>

    </InstallExecuteSequence>
    </Fragment>
</Wix>

I have also given my C# code that is supposed to get the value and write it in file:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Deployment.WindowsInstaller;

namespace SetupCAInstallFolder
{
    public class CustomActions
    {
        [CustomAction]
        public static ActionResult InstallFolderFinder(Session session)
        {
            session.Log("Here is the SetupCAInstallFolder");
            string path = session["INSTALLEDPATH"];
            session.Log("Installed Path is " + path);
            System.IO.File.WriteAllText("F:\\pathgenerated.txt", path);
            //System.IO.File.WriteAllText(path + "installed.txt", "sdkasdkasdlkasdk");

            return ActionResult.Success;
        }
    }
}

The Wix file compiles and gives MSI that doesn't get the value of INSTALLEDPATH . If I add DllEntry="InstallFolderFinder" in CustomAction tag, it fails with error The CustomAction/@DllEntry attribute cannot coexist with a previously specified attribute on this element. The CustomAction element may only have one of the following target attributes specified at a time: DllEntry, Error, ExeCommand, JScriptCall, Script, Value, or VBScriptCall

How do I pass the value of INSTALLEDPATH to C# Custom Action?

I have fixed the issue after stumbling around some more site. I have added the code in gist. The Wix File Code is here and the C# Custom action code is here . Basically I added two Custom tags in InstallExexuteSequeunce that first loads the dllentry and the second passes the parameter to Custom Action Written in C#.
