Hello Gak,

As for the default values of those variables(suc has TARGETDIR) in setup
MSI packagem, they're naturally supported in platform installer sdk. For
visual studio setup project, it only encapsulate some subset of the
functions provided by platform installer sdk(such as filesystem, regsyste
and custom action configuration).  For those setup or environment specific
variables, the visual studio setup project doesn't provide interface for us
to manipulate them(or set initial values).  So far we still have to use
some raw interfaces to configure those variables/properteis. The orca
utility is a sdk tool that support this as you've mentioned.  Also, you can
try using a script file to manipulate those properties programamtically
through the WindowsInstaller.Installer interface.

Thanks for your understanding.

Sincerely,

Steven Cheng
