Did you change it to "Program Files" or "Program Filed". Also try starting Heather with a /? command line option. This will bring up the command line help info. Scroll down to the bottom of the help info. It will have a line that says something like "Put heather.cfg" into directory... This is the directory where heather.exe is stored and the file path you should use. Besides using the "properties" entry on the HEATHER icon, you can also put the command line options that you want to use the file "heather.cfg". One command line option per line, the the "/" in column one.
