New Post: Install Target Directory

Any environment variables are accessible during pre-processing using the format ${_env_ENVVARNAME}. MSBuild properties are not. Other property name/value pairs, including any MSBuild properties, can be sent to XmlPreprocess.exe using the /d command line parameter, but to use it you'd have to override the default PreprocessBindings target, which I don't recommend. The install path is also written to the registry by an MSI deployment, but not by a Visual Studio deployment.

Are you trying to avoid referencing SSOSettingsFileReader?

Thanks,
Tom
