I am trying to update an .ini file that resides in a directory other than the one I am installing to.

I am creating an install for a 3rd party app called DocXchange that goes to "c:\program files\docxchange client". Along the way I need to update some keys in pcdocs.ini that resides in c:\docsopen\progs.

In the Ini File Changes section of the Installation Designer I have created an Ini file and set the target to a variety of values including


each value raises an error when the setup program runs.

How can I make changes to this ini file?
