Each time I have attempted to open firefox 3.6.10 after downloading is completed I receive an error message that states "Setup has caused an error in SETUP.EXE, setup will close now. Try restarting your computer and try again". I have done this for each of my last three sessions, what can I do.

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/
