Activating a licenseWhen you start Microsoft Excel, Analyse-it shows how many days of the free trial remain, or offers you a trial. Click Activate there. Use these steps if it does not appear.

Have your product key ready. It appears on your license and starts with P-.
If your computer is behind a firewall, open TCP port 443 (HTTPS) for communication to license-server.analyse-it.com.

Activate using the Windows account that will use the software. Each account holds its own license, so activating as an administrator does not activate it for anyone else.

Start Microsoft Excel to start Analyse-it.
On the Analyse-it ribbon tab, click Analyse-it, click Activate, and then click Next.
The Activate window shows the license details.
Enter the Product Key and the Name, Organisation, and E-mail of the registered user of the software, and then click Next.
The registered user receives e-mail about updates to Analyse-it. They can unsubscribe using the link in the e-mail.
If activation fails, activate manually:
1. Click Get Activation Code.
  Your browser opens the manual activation page at analyse-it.com/activate, with the details from the Activate window already filled in.
2. If the computer has no internet connection, open that page on any other computer or device, and enter the Product Key, Site ID, Name, Organisation, and E-mail shown on the Activate window.
  
  Important: The Site ID identifies the computer and Windows account. It only shows on the Activate window in the software, so do not contact technical support asking for it. We cannot provide it.
3. Click Get Activation Code.
  The activation code shows in your browser window.
4. In the Activate window, enter the Activation code, and then click Next.
Click Close.
