problem in deployment

[C# Programming]

I am using Iexpress.exe to package all installation files(setup.exe,msi,.net framework etc) into single exe.

But the exe is not working.

I have created a batch file including following:
@ECHO OFF
CLS
MD dotnetfx
MOVE /-Y dotnetfx.exe dotnetfx
MOVE /-Y instmsia.ext dotnetfx
MOVE /-Y WindowsInstaller-KB893803-v2-x86.exe dotnetfx
EXIT

And selecting batch file,setup.exe and msi file in iexpress.exe for creating package.

Got the single exe but while installation i am getting:

This installation package could not be opened. Verify that the package exists and that you can access it or contact the application vendor to verify that this is a vlaid windows installer package.

And InstallLog file shows:

Please give me clue where I am going wrong.
