if all of you really facing the problem of microsoft bootstrapper not working, then rather than trying those method you can simply first uninstall offfice 2013 or 365 if you have previously installed. Coz the Bootstrapper problem is simply the the previous file corrupted that won't let to install new one so follow my step in manually uninstalling the previous office of 2013 or 365 from files, your registry and all remaining dumps from ua computer.

Manually uninstall Office 2013 or Office 365

Applies To: Office 2013

NOTE: Before you start, you need to know removing Office manually is a long, complex process and might require that you reinstall the operating system if certain steps are done incorrectly.

You'll need to determine your Office installation type so you can choose the correct way to uninstall it:

• Click-to-Run is a new way to install and update Office over the Internet and it works similarly to streaming video. By default, Office 365, including Office 2013 products are installed by using Click-to-Run.
• MSI, (also known as the Microsoft Windows Installer), is the traditional way of installing Office via a local installation resource.

   To determine your installation type

1. Start an Office application, such as Word.
2. Click File > Account.
3. If Office 2013 was installed using Click-to-Run, an Update Options appears. For an MSI installation, the Update Optionsare installed through Windows Update only.
