I developed a C# application which needs several data files.  I want to
install them in a subdirectory of my install directory.  In addition, I want
to set some registry strings to point to these files.  I can get setup to
install the files fine.  I can set the registry string values to the correct
paths if I use something like:

[ProgramFilesFolder][Manufacturer]\[ProductName]\WaveFiles\InvalidInput.wav

However, if, at the time of install, I specify a different directory then
the proposed default then this still sets my registry key to the c:\program
files... directory.

How do I set a registry string value from setup to contain the actual
location my location was installed too?

Thanks!
