Overview
This guide covers installing Lumivero @Risk from a downloaded installer and activating it with a license key. The installer must already be downloaded; a separate download article exists.
Prerequisites
- The @Risk installer, already downloaded to the computer (location varies; often the Downloads folder).
- The Lumivero @Risk license key (source of the key not recorded in the original instructions; confirm with the team that manages software licensing).
- Permission to install software on the computer (administrator rights requirement not recorded).
- Operating system and @Risk version requirements (version not recorded).
Steps
Locate the downloaded installer and double-click it to start the installation.

Select OK.
Select Next.
Accept the terms of the service agreement.
Select Next.
Select the option to activate the license.
Paste the license key into the license key field.
Select Next.
Select Next again on the following screen.
Select Install.
When installation completes, select Finish.
Verification
- Open Microsoft Excel. @Risk installs as an Excel add-in (assumed from the product; not stated in the original instructions).
- Confirm that an @Risk tab or menu is present.
- Confirm that the software does not show a license or activation error on launch.
- If activation fails, re-check that the license key was pasted in full with no extra spaces, and repeat the activation steps.
