I found on the compability windows website that this version is not compatible with windows 8. What to do???
Do you mean Version 6, not CS6? Then you have to buy a new version, either CS6 or subscribe to CC.
It is indeed Photoshop 6.0 and not CS6
Is there an upgrade from 6.0 to CS6 possible?
No, it is too old. Version 6 came around 1999
