Dreamweaver 8 and Windows 11

I kind of doubt it.  Macromedia DW8 from early 2000's was built to run on Windows ME/2000, XP or Vista.

But the nail in the coffin is activation.  The aged-out activation servers don't exist anymore.  Even if you manage to install the software, it's impossible to activate your license beyond the trial.  After 30 days it will become useless.

That said, you shouldn't be using 2 decades old, obsolete web software for modern websites. Too much has changed.
