Moving ExtendSim from one device to another works the same as for most applications.

First, make copies of your ExtendSim models, any custom blocks, etc.

Remove the license from the previous device using the Help > Revoke License command (or the Hlep > Deactivate ExtendSim command if prior to 10.0.5).

Then, use the Windows Settings > Apps and Features to uninstall ExtendSim 10 on the first device.

Then delete the two folders: Documents/ExtendSim and Program Files/ExtendSim.

Install ExtendSim on the new device by downloading the appropriate Trial version.

Paste your model files, etc. from the previous device to the new installation of ExtendSim.

Launch ExtendSim on the new device and activate it using the same Activation Key you used for the first installation. (If you can't deactivate ExtendSim on the previous device, you will get an error message stating your Activation Key is already in use on another device. In this case, contact Imagine That Inc.)
