TRNSYS Licence Activation
Register your TRNSYS 18 licence directly using the form below. Complete the fields with your details and licence information, then submit. There is no need to email us.
Before you start
Your machine code
Open TRNSYS Simulation Studio on the computer you are licensing. The machine code is the code displayed on screen when it opens. Copy it exactly as shown.
Your username
This is the email address the licence is registered against, which is not necessarily your own address. If a colleague arranged the purchase, use the address they gave us at the time.
The form can take around 5 seconds to appear. It is hosted by CSTB, the licence authority, so it loads from their server rather than ours. Please be patient and do not refresh the page while you wait.
Still nothing after 10 seconds? Open the registration form in a new tab. If your details are rejected, check that the username is the address the licence is registered against, then contact us and we will help.
