I'm new to Firefox. I can't install it. Windows give message this is not a Win32 application. How do I install the setup?

Firefox

When I click on setup icon for Firefox, I get 'this is not a valid Win32 application'. I don't have any other details I could give. It simply just doesn't load or open.

Oh, we are sorry for that. Download 7-Zip from(http://www.7-zip.org/). Install 7-Zip. Download Mozilla Firefox from (http://www.mozilla.com/en-US/products/download.html?product=firefox-3.6.13&os=win&lang=en-US). Now instead of opening Firefox Setup, right-click it, click 7-Zip and then choose Extract to "Firefox Setup 3.6.13"\. A new folder with the name Firefox Setup 3.6.13 will be created. Double-click Setup.exe in the Firefox Setup 3.6.13 folder.
