Can i get CS6 to work in high sierra?

Yes you should be able to. You will need to download and then install this for the apps to work, Download Java for OS X 2017-001

Also have a look at this, https://roaringapps.com/ click on view macOS apps, and then type in Adobe CS6 in the search field on the right, now go to the left of the screen and change the figure in the Display dropdown to 25.

What happens when you try to use it?
