What is activation?

Expression Studio 4.0

Activation helps verify that your Microsoft Expression product is genuine and that it has not been used on more computers than the Microsoft Software License Terms allow. In this way, activation helps prevent software counterfeiting. Activation of your Expression product is required.


The information collected during activation will not be used to contact you.

Setup will automatically attempt to activate your Expression product during installation. If automatic activation fails, or if you choose not to activate your Expression product during installation, you will have 60 days after installing your Expression product to activate it online or by phone.
