I know how to make properties available to a deferred cudtom action in a Basic MSI project. My question is: Is the INSTALLDIR property not available when uninstalling via Add/Remove Programs? If not, how can I reference something that is in there?
The INSTALLDIR property should be set to the installation location of any installed components, so as long as one or more components were installed with a destination of INSTALLDIR, it will be valid.
