Emperor Battle For DUNE Setup found and Question

The 1.04 setup is on game copy world along with fixed .exes for the game.

My question.
1. whats the easiest way to get the cracked setup on the CD so i can install the game.

2. once the cracked setup is implemented is it recomended to leave the game at ver. 1.04 or is it ok to upgrade to current 1.07 (what a crap coding dept they have 7 patches allready? sheesh)
