All that I have read is that 4.5 is not compatable with any other DAZ program. OK this means you can use all of your DAZ apps but you cannot have DAZ3 or DAZ4 on the same puter as DAZ4.5 and that DAZ5 may be out at anytime so it is up to you. as for me I am holding off 4.5 untill 5 is out.

I will also add that if you need other males STIX has a few also do a search on SG and Rend you will find lots of them
