What is iolo's Whole Home License?

The Whole Home License® is iolo’s licensing policy that allows you to install and keep your software running on all of your compatible devices within the same home. Previously, users were allowed to install and license their iolo software simultaneously on a maximum of three PCs. Under the Whole Home License, a single activation key allows you to use your iolo software on all of your PCs, other than any PCs you use for business purposes. What you need to know about Whole Home Licensing
