Microsoft Windows Update for Centrino Wireless-n 10130

Windows update stopped the Intel Centrino Wireless-n 10130 update and a blue window popped up stating:

========================
"Intel PROSet/Wireless Software v17.14.0

Installation Blocked:

This version can not upgrade from the current older product. Please uninstall the older product manually.

Please resolve these erros and rety Installation."

A button with check mark & Finish is the last thing in the popup window.

=================================

I have two questions:

1. Is it a good idea to to install this generic Intel driver or does Dell have its own update?

2. How is a Wireless driver correctly uninstalled & will I need an cable Ethernet connection while the Wireless is updating?

Inspiron 17R (N7110, Early 2011)
