Using Explorer, the default browser on my new computer, I went to the Mozilla.org site and clicked the link to download Firefox. A prompt appears at the bottom asking if I want to run the program, and I click "yes." The green status bar appears, gets to 61%, disappears, and another box appears asking if I want to allow Mozilla Corporation to make changes to my computer. I click "yes," the box closes, and nothing happens. I went through the install process by saving the file to my downloads instead of running it immediately; got the same result. I cannot get past this point to the Mozilla setup wizard to install the browser. Any help with this would be greatly appreciated. Thanks in advance.
