The default installatation is "%PROGRAMFILES%\digestIT 2004" at least for Windows XP. I found it was installed in "C:\" when I installed it on a Windows 2000 Professional SP 4 system using wpkg, however. You can specify the installation directory in the digestIT 2004 entry in the packages.xml file by using an entry like the following in the install section:
<install cmd='msiexec /i "%SOFTWARE%\digestIT2004\digestIT 2004.msi"
/qn TARGETDIR="%PROGRAMFILES%\Utilities\File\digestIT 2004"' />
You could use the entry above to install the program into "C:\Program Files\Utilities\File\digestIT 2004". The installation process would create any of the subdirectories that did not exist.
