You should deactivate your NVivo license key:

• Before transferring the license key to a different user.
• Prior to uninstalling NVivo, or moving NVivo to a new computer.
• Prior to reformatting or reimaging your computer.

If you no longer have access to the device, a single user license does allow a license to be activated by the same user on up to 2 devices. 

To deactivate your license key, ensure that you are connected to the Internet and then follow the steps below:

1. Close any projects you have open (File > Close), saving projects when prompted if appropriate.

• NVivo 15 for Windows, NVivo 14 for Windows, NVivo 13 for Windows: Click on the File tab, point to Product Info, Manage License and click Deactivate License.
• NVivo 12 for Windows or NVivo 11 for Windows or NVivo 10 for Windows: Click on the File tab, point to Help, point to Manage License and click Deactivate License. Click Yes to confirm.
• NVivo 15 for Mac, NVivo 14 for Mac, NVivo 13 for Mac, NVivo 12 for Mac, NVivo 11 for Mac and NVivo 10 for Mac: Click on the NVivo menu, point to Licensing and click on Deactivate. Click Deactivate again to deactivate the license.  A message is displayed to confirm that the license has been deactivated.

2. Click OK
3. The NVivo application automatically closes.

Note: Deactivating your license key does not affect your projects. Your projects are by default stored in your Documents folder and have a file extension of:

• Windows: .nvp if you are using NVivo 15, NVivo 14, NVivo 12, NVivo 11 or NVivo 10
• Mac: .nvpx if you are using NVivo 15, NVivo 14, NVivo 12, NVivo 11 or NVivo 10
