Cannot install Windows Live Mail

I am hoping someone can help me. I have vista home prem. 32, I have had Windows live mail on my laptop since i have had it. About a month ago, i upgraded it to the newer version. Now it will not install it, i can't even install the old version. I have tried everything. I have disabled the fire wall, virus program, ran it as administrator. Everytime i try to install it, it comes up saying it can not install and try again or checked the items i just listed. Does anyone have any Idea. I really like the Program and would rather use it then going into the hotmail website to get my mail, especially since i have more then one email account.
