CS6 I can´t find it

adobe's no longer selling cs6 so it's not clear what you bought if it was purchased today.

if you purchased cs6 years ago, your serial number is still valid and you can download the cs6 installation files using the link(s) below.

note: newer os'es (especially mac os'es) are not compatible with older programs (especially adobe's).  this may help you start your installation, https://helpx.adobe.com/x-productkb/global/macos-high-sierra-compatibility.html that said, you can download the installation files using the below link.

• Download and installation help for Adobe links

• Download and installation help for Prodesigntools links are listed on most linked pages.  They are critical; especially steps 1, 2 and 3 which also apply to eLearning Sute 2.5.  If you click a link that does not have those steps listed, open a second window using the Lightroom 3 link to see those 'Important Instructions'.

And a big thank you to Jim @ Prodesigntools for helping me with these links!
