On basic MSI project What is the best way to install components relative to the INSTALLDIR ? For example if the user choose to install the setup under C:\Program Files\Company\TEST\ ( which is now INSTALLDIR ) I want that several components will be installed under the C:\Program Files\Company\ directory.
I think you'll need to write a CA that gets the parent directory of INSTALLDIR then use MsiSetTargetPath to modify the directory associated with those components.
