Installing or updating the app
Save your work, close ThermoFluid Studio, and run the latest Windows installer. Back up your projects before updating.
The installer is unsigned. Windows may show an unknown-publisher warning. Check the published SHA-256 and follow your organization's installation policy.
Activation and computer limits
Open Help → Sign In & Activate License and enter your email and license key. Use the email from your purchase or gift license.
Your license supports up to 3 active computers. Sign out of an installation to release its slot. Contact support if the old computer is unavailable.
