Dreamweaver CSS 5.5 kann nicht installiert werden.

Windows 11  Nach Eingabe der Serien Nr. kommt ein grüner Hacken für Ok. Aber die Weitertaste bleibt ausgegraut. Als Testversion gleiches Resultat. Weiss jemand mehr ? Besten Dank

CS5.5 from 2010 is not certified to work on Win11.  It might work or it might not.  That's the risk you take.  You could try installing CS5 in  compatibility mode.  But I can't guarantee that will work either.  Computers have changed too much in 10+ years. 

Similarly, obsolete web authoring software has zero value today.  The web has changed too much.  

Best advice, get a modern code editor.  😉
