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

  • You, your spouse, and your relatives living within the same household may use the same license on any number of PCs that you own which are not used for business.
  • For full legal terms and conditions, see https://www.iolo.com/company/legal/eula/

To install your iolo product on additional PCs:

  1. On the additional computer, download the latest version of your iolo product. Choose from the list of downloads offered here.
  2. Follow the steps in the installation wizard, and enter the same Activation Key that you used to install on your original computer.

You can view the Activation Key on the original computer from within System Mechanic > red menu bar > key icon > Activation Key.
