cs 6 from mac to windows

Beware of fake Adobe reps who may contact you privately offering to sell you software or take control of your computer. It's a scam, run away! Real Adobe employees will never reach out via Outlook, Yahoo, Gmail or Skype.

3 Easy Ways to Identify Genuine Adobe Staff

No-can-do.  You need a special Windows license but Adobe no longer issues them for discontinued software.  CS6 is too old.

Option 1: Get modern Dreamweaver CC by subscription.  It works on Windows/Mac or both.

Option 2:  Use another code editor that will work with Windows.

CODE EDITORS:
-- Codespaces (free, browser-based) - https://github.com/features/codespaces
-- Pinegrow - https://pinegrow.com/
-- Sublime Text - http://www.sublimetext.com/
-- Visual Studio Code (free) - https://code.visualstudio.com/
-- Wappler ~ Visual Web App Builder - https://wappler.io/

CS6 is no longer sold or supported by Adobe. You used to be able to request a one time language swap for the program, from Mac/Win or Win/Mac, but they no longer offer that service.

If you get a CC subscription, you can install DW on either or both system types.

The customer service rep should have been able to tell you that without passing you off to the forum.
