They might need Expression Web for compatibility with older projects or websites. Alternatives today would include Visual Studio Code, Adobe Dreamweaver, Sublime Text, or even using Visual Studio with web development tools. I should mention those. Also, maybe guide them on where to find official downloads safely, like through Microsoft's archive or through a Microsoft account if they have a license. But again, not sure such links are still available. Also, note that any license for Expression Studio 4 is likely expired.
