Windows Installer Patch

[C# Programming]

Hi,

I have my project in c# and I have its setup project.

To update my existing clients with latest changes, I require to create a Windows Installer Patch.

I could create a patch with MsiMsp.exe, but however my patch does not update the existing application. Changes are not reflected... I would have missed some configuration or set them wronghttp://www.barakasoft.com/script/Forums/Images/smiley_frown.gif

Can anyone help to get one by one steps to create a Windows Installer Patch?

Regards,
