# Can I change my computer name and upgrade my computer system once Rhyme Genie has been activated?

{% hint style="success" %}
**Windows and Mac version:**

You can change your hard drive or install a new operating system and your **activation code will remain valid** and can be used to unlock a newly installed version of Rhyme Genie.

The only thing that will render the activation code invalid is a change of your computer hardware ID and/or a change in all your NIC addresses.

**iOS version:**

You may run the app on all **compatible iOS devices** linked to your Apple ID.
