Cannot open Firefox 19.0 to install after the download

I'm currently under Firefox ESR 17.0.3. It cannot automatically update the latest versions and tells me to do it manually, but that no longer works. After d/l 19.0.1 and 19.0.2, all two setup .exe liquidation timing after opening almost complete, saying that "access is denied zip 7. I will not delete my current version without lifting the update and running. What is going on???

Please make sure that you are the administrator of the computer, that no firewall blocking access to it and try a restart of the pc.
