Reactivating on a New Computer

Applies to: LoopCAD 2021, HeatCAD 2021, PlumbingCAD 2021

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 "Update my current Activation" link.
  4. You will be prompted to login to your account to complete the remaining steps. (If you forget your password use the "Forgot Password" link to have it sent to your email.)
  5. After you have completed the process your new Activation Code will be automatically applied, and a copy will sent to you by email. (If you later need to manually enter the Activation Code, see the Entering an Activation Code help topic.)
