Secondary Activation for Personal Use

Applies to: LoopCAD 2019, HeatCAD 2019, PlumbingCAD 2019

The software is licensed on a per-user basis, and a single license cannot be used by multiple users. However secondary activations are available at no charge as long as it is for use by the same person as the primary activation. This is to allow for the licensed user to use the program on their work computer and on a laptop or home computer

If the second activation is for a different user, then a new license must be purchased for that user.

Once you have the software installed, follow these steps to purchase and activate your license. 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 "Activate on a Secondary Computer..." link.
  4. The website will now open with the option "Activate a secondary license..." 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.
