Since you will probably not be able to access the internet to automatically activate ExtendSim, follow the instructions for Manual Activation of ExtendSim in the Installing & Activating • Individual Licenses document.

When you click the Save Activation Info as Text File and generate the text file ExtendSim Activation Info.txt, copy its information and email it to This email address is being protected from spambots. You need JavaScript enabled to view it..

When we email back the license file extendsim.lic, copy or print the contents of that license file.

Using the information from the license file, create a text file on the secure device (use Notepad or right-click on the desktop to create a new text document).

Name the text file on the secure computer extendsim.lic.

Place it in the folder that contains the user-modifiable files (by default, UserName\Documents\ExtendSim).

Restart ExtendSim.
