Wow. thanks to all you people who answered my question about loading poser into Vista. It worked just fine. Excellent article on 99 tips for vista!!
So I loaded poser but put it into the program directory because it seemed that once I had freed User Account Control the programs would load. This may have been a big mistake because now I cannot manually install several programs.
So I have two big and related questions:

1. I have to manually load several zip packages into poser 7. In windows xp all I had to do was unzip the folders into the Poser 7 directory and it loaded them. But in Vista it will not extract the files when I do that. How can I make vista extract those files?
   I have already turned off User Account Control, which I needed to do to load poser.

2. How do I give users Roxanne PC full control?
   How do I sign on to be the administrator?
   e.g. when I try to delete a folder with runtime files that did not load properly from Poser 7, it tells me I need permission to do so. I have tried to set the security settings so that users have full control but it won't let me affect that - I get a blank form to fill in saying "enter object name to select" What is that? or it tells me that user Roxanne has full control but says properties not inherited from anywhere.

I am not sure that I can just delete poser and start over loading poser into the base directory because it seems as a user I don't have the authority to remove the program
