At present am downloading LibreOffice v. 4.6.6 Win x64
currently I have installed Open Office v. 4 but would like to switch to Libre Office
Excellent move.
If your Windows 7 is a 32-bit system (assuming that’s what you meant by X32) then download the 32-bit installer from the download page, select Windows (32-bit) from the Choose your operating system listbox if it’s not predetected.
