Am I really so retarded??

So finally got my Poser 7 disc sent to me again (I left it in Scotland), installed it on this computer. But can I get V4 to fucking work? No.

I've tried installing her numerous times, in program files, e frontier, poser 7, runtime. I get the icon for her but she wont load, it keeps saying it cant find body groups and stuff?? So I go back to install, it gives the option of target application. If I choose Poser 7 it wont even install cos it says I have to put it in an executable directory. So I choose DAZ and it lets me browse where I want to put it and I manually pick the poser folder etc.

I'm loving the zip files from Rendo etc cos two clicks and they're installed, but stuff I buy from DAZ I'm obviously fucking up majorly.

I'm really friggin frustrated and if I had any bloody hair I'd have pulled it all out!
