EULA errors appear during setup from custom-made CDs and or floppies.
SetupSourcePath specifies the path relative to the source device where the
setup source tree is to be found. All media descriptors are relative to
this. Check SetupSourcePath value (usually it's a backslash \) and make sure
the file %SetupSourcePath%\i386\EULA.TXT is present.
Unattended setup skips EULA checking (it assumes EULA has been read).
