There are a plethora of ways to install LibreOffice, and each one has it’s benefits for various operation systems or environments.
One of the best ways I’ve found to install LibreOffice for Microsoft Windows is to use a tool called Ninite (Read the review of it on Lifehacker). It’s simply a small program that will handle installation, and also upgrades, whenever you run it.
The simplest way is to head to Ninite’s website, and then select LibreOffice out of all the choices. It’s listed under the Documents section. Then on the bottom of the page, click Get Your Ninite, and the small program will be prompted to be saved. Go ahead and pick a location on your computer that you will remember.
Then go ahead and run it, or navigate to your saved location and double click the program Ninite LibreOffice Installer.exe and it will start. Windows may as you to allow Ninite to install the program, and click yes to proceed. After that, there are no dialogs or anything else to click through.
One of the great benefits I like about Ninite is that it handles updates as well. All you have to do is run the Ninite program from your computer whenever you want to upgrade LibreOffice.
The beauty of Ninite is that you can install/update multiple programs besides LibreOffice in one fell swoop, without the headache of managing each one whenever those programs notifies you of a new available version. Just close your programs, run Ninite and let it handle that for you!
