normally, ACE should do all the work, just put the entire folder in the variants folder.

however, to be sure, I'll check again on my system here.

EDIT: Can't find the reason it's not working with you. Tried them again here, and no problems whatsoever.

If it won't do it, I'd suggest manual installation.
the CH-04 should be put in the CS_C130 folder in your simobjects, the CH-07 in the CS_EX2_C130 folder then update the aircraft.cfg files with the information provided in the descrition.

I hope this helps...
