I am trying to upgrade Firefox on a laptop that currently has 2.0. I downloaded 3.6.3 and opened setup. I get an error message indicating that setup cannot run setup.exe. It advises I restart my computer. When I do, it does no good. Please advise.

This happened

Just once or twice

 You have an old version of Windows installed. See http://www.mozilla.com/en-US/firefox/system-requirements.html

Firefox 2.0.0.20 is the last ever version of Firefox for Win98 / SE / ME.

You can try KernelEx to get Firefox 3+ to work, but it would be very slow with an old PC of less than 750Mhz. http://sourceforge.net/projects/kernelex/
