Windows only: When you try to open a project file, you see the following warning: SECURITY RISK Microsoft has blocked macros from running because the source of this file is untrusted. Macros for the project file do not run and the project cannot be completed.
Cause
Microsoft changed a security policy for Office to block all macros from the internet by default. While intended to improve security, this policy change also blocks many legitimate macros, including those required for some SAM projects.
Resolution
Add cengage.com as a trusted domain to enable macros for your SAM projects.
