Thank you for upgrading to ExtendSim DE 10!
While we process your request for an activation code, here's how you can get started...

1. Download ExtendSim DE (if you have not already done so)
This is the full, Model Developer Edition of ExtendSim DE. Convert your older ExtendSim models to 10, modify them, analyze results, build new ones, etc. Every model and block you update or build while in trial mode will transfer seamlessly once you activate the software.
2. Acquire your Activation Code
You've already taken the first step. The Activation Code will be emailed to the registered user once Maintenance Plan status has been confirmed, payment processed, or PO approved. In the meantime, you have 30 days to use ExtendSim DE in Trial mode.
3. Activate ExtendSim DE
Once you receive your Activation Code from us, launch ExtendSim DE. Select Activate from the Activation dialog window. Enter your 16-digit code plus your name, email, and company. You're good to go!
Happy Modeling!
