CS6 was a different version (i.e. not a free upgrade). When it was sold it could be bought at full price or at a reduced price if you had the previous version. However you can no longer buy CS6 either as new app or as an upgrade.
If you already have a license key for CS6 then the link Mylenium gave you will enable you to download.
I have purchased CS6 upgrade German version of Mac. Now I have a new windows pc. I want to try to activate a windows version with the mac code. What else can I do?
Kind regards Tom
Since CS6 is no longer marked it is not a current version of an Adobe product. A platform switch may no longer be an option.
Adobe Subscription software is not tied to any Platform however some Adobe software only work on machine that run the right OS.
Some Adone apps are developed to devicess the run IOS and Android. Other Adobe Products requires OSX or Widows Adobe doe not support other Operating systems Like Linus, Unix. AIX and mainframe operating systems.
You must use the required Hardware and OS for the products you want to use.
