hi,
yes, im getting the same error, and i think i know, why it occours!
the path "\$OEM$\$1\D\C\I\xp\" is not existing in my cd-directory! there is a second "D" directory in the tree, sometink like that:
"\$OEM$\$1\D\D\C\I\xp\"
so the setup cant copy a file, that dosnt exist, because the path is wrong!
i think that is a bug 
and yes, im using it without QSC...
