Your Reference Number (aka Order ID/Number), which looks like ENT1202031234 is the registration code. This and the email that you gave while ordering are the only two things that you require to activate the product. Please see this for Step by Step installation procedure. For your convenience, we email the license to you as soon as your order is processed. Please check your junk mail folder as it might have gone there. If you have lost it, you just need your Reference Number and Email Id to be entered into ETS License dialog box to let it download the license automatically.

If you do not receive Reference Number and/or License from us within 2 hrs of purchase, please contact us immediately so that we can investigate the issue.
