If you got the standard "stub" download, could you try the "full" installer. You can get that from the following page (scroll down to your preferred language):

I think in an earlier thread it was reported that Firefox installers include decompression technology from 7-zip. Is Windows reporting or recording any error involving 7-zip?

Hello rappin05, try to boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) and then see if that allows to download and install Firefox from the next full installer link

thank you

@jscher2000 Tried this, the extraction goes to the end of the bar and then the process just ends, i would have mentioned an error

@ideato Safe mode combined with the full install worked just fine, thank you. Things really do install better with nothing else going on
