try to use this hope this will work for you

It's important to note that the '-setDefaultBrowser' switch isn't supported by the installer, but only by the firefox.exe executable in '%programfiles%\Mozilla Firefox'...

here is a regfile with the captured reg-entries that Firefox v2.0.0.4 added when selecting OK to make it the default browser
