Is there a way to automatically retrieve the value of INSTALLDIR from the original setup in a consequent upgrade setup?
I need to run a batch in an upgrade setup and I would expect InstallScript to keep the value of INSTALLDIR for me but it doesn't.
I know I can store the value in the registry myself and read it in the upgrade but I'm wondering if there is another way...

You could use the AppSearch feature to search for the signature of your main EXE, or Installshield MAY have stored the value in ARP:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{GUID}. Look for InstallLocation or similar.

A configurable option in Installshield setups:

ARPINSTALLLOCATION This property stores the fully qualified path to the application's primary folder. You can set ARPINSTALLLOCATION to the value of INSTALLDIR with a custom action of type “Set a property”.

@Stein: your reply applies to MSI projects, but joegilad is using an InstallScript project.

@joegilad: if I recall correctly the value is automatically restored, unless you override this behaviour in your script. As a try remove all your script code, or create a new test project using only the default code, and see if it works.

Sorry! :-). When I use the "recent posts" view these things happen.
