vista is blocking my machine to launch mozilla, chrome or safari, can any body help

[Guest freshman]

I just got a new machine with windows vista pre loaded. every thing

worked fine but when I tried to install an internet browser other than

internet explorer (mozilla firefox, google chrome, safari), it allows me

to down load, install, but when the new browser is about to launch, the

machine sends a message (for mozilla), that says "the security component

for the application could not be initialized, most probable cause is,

problems with the application profile directory files,(for google

chrome) installation error No 2, (for safari) it just frozen. I have

tried every thing I know, that it is very little, because I am not a

computers man, I am an user. I setted the "privacy" rectriction in

Internet options" to allow the new program to go through, same I did the

same for the "fire wall", and "emerging" elements, and still can not get

any of these internet browsers launched in my machine. I will

appreciate any comment or direction that might help.
