Hi:

We have an application that we install on a local machine. We have another application that calls the installed application. However, for the second application to know where the first application was installed, I need to write the installation path to a registry key. I have been looking over the installer project I have created and there doesn't seem to be a way to retain the installation path once the user has selected it.

Application.startuppath doesn't work since setup.exe is the calling application, not the application being installed. My plan is to insert a custom install action to write the install path to the registry before the installer exits. I just need to now how to get the install path (after the user has selected it).

I apologize if this is a stupid question, but I assumed it would be relatively easy to get and I haven't been able to find it yet.
