Use this page to update existing Windows or Macintosh RATS licenses to version 10.0. These are special discounted prices, which we are offering during the period through 30 September 2021 to help researchers who may be locked out of their offices, or have their purchasing departments closed down. Note that this is available to anyone, regardless of how they have been affected.
Note: If your serial number begins with WX (Windows) or MX (Macintosh), you have the Professional version. If it begins with WE, WP, WS (Windows), MP, or M2 (Macintosh), you have the standard version.
