Need to prevent uninstall and install during the upgrade scenario

Currently we are using installshield 2012, whenever we upgrade the product, the product get uninstalled and again installed. By doing this, we can't maintain customer logged in state. Can we prevent this by just replacing the file when we do upgrade?

Appreciating your help in advance

Regards,
Selva

Perhaps your application should support Restart Manager.
