Reloading 2004 version Dreamweaver

Even if you could find an old supporting computer for it, MX 2004 is so woefully outdated now that nobody should be using it.  The web has changed too much in 18 years!

Hope that helps.

DW MX is seriously ancient by both internet and operating system standards. If you can get it to run at all on a modern machine, this page may help you get past the activation issue: https://helpx.adobe.com/x-productkb/policy-pricing/macromedia-legacy-activation-error.html 

All versions prior to Creative Cloud are either EOL or on life support. Adobe no longer sells, supports or updates any of them, and the activation servers for the oldest versions are simply gone.
