Firstly, we don't talk about cracks here.
What software did you use to image/burn the games?
What reader/burner did you use?
What media have you used?
LOTR : ROTK 's cds. Disc one has no protection, Disc two has no protection, and disc three has SafeDisc on it.
Have you checked this forum?
If you are installing/playing from a burner, do you have an ATIP hider activated (Alcohol 120%'s Ignore Media Type of CloneCD's Hide CDR media) option?
BTW, that file you were looking for, it is probably in a setup .CAB and they can mostly only be open by the setup file.
