Instal error CS6
Hi Guy's,
Having trouble installing CS6 on my new MacBook Air. Baught CS6 in 2013 (£950) but when trying to instal it on my new MacBook the Red instal file has a white circle with a line through it (a bit like a no entry road sign). When I click on it a message comes up..... .

"Instal" needs to be updated.
The developer of this app needs to update it to work with this version of macOS. Contact the developer for more information.
Does anyone know how to get round this please?
Any hope woukld be greatly appreciated.
