3. What is activation?

   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.

   Note: 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.

Known Issues

1. Upgrading Silverlight 3 projects to Silverlight 4

   When you attempt to open a Silverlight 3 project, Expression Blend 4 will offer to upgrade the project to Silverlight 4. If the upgraded project references controls in the Silverlight 3 Toolkit then you are encouraged to install the Silverlight 4 Toolkit and then clean and rebuild your project. If the upgraded project references the Viewbox control, be aware that this has now moved from the Toolkit into the platform so you’ll need to change the following XAML:

   <controlstoolkit:viewbox... />
to
<viewbox... />
