I am building a project in C# using a setup project. I have included an installer class with the onafterinstall event handler. I would like to be able to get the path the user started the installation from, as this could be a network install, cd install, etc. I haven't quite been able to narrow this down, searched google, tried System.Deployment, System.Environment, System.Reflection namespaces to no avail. Can anyone help me here please?
