  1. Firefox 32bit installs by default on 64bit system. Why?


    So I was helping my nephew with a new netbook setup. It's running Windows 10 version 1909 64bit. The specs are quite low, so I'm guessing that's why this is happening, but I download the Firefox installer from Mozilla's main page, and it is installing the 32bit version. I'm just trying to get some opinions of the real reason why.

    :)

    32bit or 64bit???

    Just to let you know VISTA 64 works well.
    If you have VISTA 32bit on your system you will need to do a reformat of your hard disc, for some reason VISTA 64bit does not install over 32bit OS.

  3. 32bit to 64bit

    You can run 32bit Setup from a 64bit desktop because a 32bit program can run on 64bits so a "down"grade will run.

    But you cannot run 64bit Setup from a 32 bit desktop because a 64bit program cannot run on 32bits, so Bilal's reply is correct since the OP is going from 32bit to 64bit.

    When, as in your case, you go from 64bits to 32bits you may find you have a Programs (x86) folder, which a 32bit version of Windows should absolutely not have. There are other anomolies. It is because the 32bit installer cannot remove certain 64bit elements
    of the old OS.

    It is not a good idea to "down"grade the architecture. It is safer to do a clean install of 32bits.

    You may have a confused OS. I have done this (back when 64bit Windows first released) and I have no confidence in the results.
