If your site has been issued multiple NVivo license keys and you encounter problems activating a particular license key—for example, if a license key has expired or has been activated too many times—then, you can use a different license key instead.
You can replace a license through the software in one of two ways:
If you are prompted to activate your license when you start NVivo—click Replace License Key, enter your new license key and then click OK.
If you are not prompted to activate your license key when you start NVivo, then do the following:
Choose NVivo > Licensing > Replace License.
Enter your new license key and click Next.
