Reactivating on a New Computer

Applies to: LoopCAD 2020, HeatCAD 2020, PlumbingCAD 2019

If you are moving the software to a new or different computer, or you have changed hardware components in your existing computer, you will require a new Activation Code. Once you have the software installed, follow these steps to activate your new installation.

If you need the setup file to install the software, go to the corresponding downloads page:

  1. Run the program on the computer that you want activated.
  2. If the Activation window does not automatically open, click the Activate link.
  3. Click the "Reactivate on a New or Different Computer..." link.
  4. The website will now open with the option "Activate after a reinstall..." selected. Click Continue to proceed.

    Do not change the Install ID that is automatically displayed on the website form.

  5. Click Continue and follow the remaining steps to login to your account and complete the process. (If you forget your password use the "Forgot Password" link to have it sent to your email.)
  6. After the request has been sent you will receive an email with your new Activation Code. For help on entering the Activation Code, see the Entering an Activation Code help topic.
