I've just started looking into this unattended stuff last night, but I've been making custom FC installers for years, and starting with FC8 it's become a very trivial task. This should work if my first hours of reading has paid off $OEM$/$Progs/FirstClass/fcc32.exe $OEM$/$$/System32/fc.ico fcsettings.reg =========== Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOT\FCIC32\DefaultIcon] @="%SystemRoot%\\System32\\fc.ico" =========== Custom settingsfiles goes into $OEM$/$Progs/FirstClass/settings/*.fc fcc32.exe will autogenerate all needed files, folders & registry entries (including "mapping" <.fc> to <fcic32> for legacy reasons) except the settingsfile icon and it's "association" to .fc (fcic32). It will also copy (all in $Progs/FirstClass) /Download, /fcp, /plugins, /settings and /tools along with their contents to <current user>/My Documents/FirstClass on every run if they doesn't exist to accomodate multi user environments.
