I converted an MSI into an Installshield 2015 project by opening it in Installshield and choosing wizard.
The files in the project do not have path variable "link to" for them. Is there a way to create a path variable for them without removing and re-adding all of the files, so that I can build the project from command line and set the path variable using the -l parameter?
Use the Convert Source Paths Wizard: on the Project menu, click Convert Source Paths.
