Using Installshield silent install setup.exe -r a setup.iss file is created. It has a line that reads szdir=C:\Program Files\Prog_Name where the program files are installed. I wish to know if there is a way to use Windows Environment Variables,eg. %PROGRAMFILES% as szdir value so that the program may be installed in computers with different system drive letters eg. E:\Program Files\Prog_Name N:\Program Files\Prog_Name Thanks to all who bother to answer.
