Flight Deck 4

I installed the Abacus Flight Deck 4 for FS2004 and FSX however, its giving me problems with the installation of the Scenery. When I try installing it in FS2004, it kep telling me that it cannot find FS2004. When I tried installing the Scenery in FSX, it kept telling me that FSX is not in the Windows Registry. Any help on this?
