How to install Adobe Photoshop CS5 from 2011 on macOS Sierra?

Hello

I have bought a license of Adobe Photoshop CS5 in 2011 for 924€ and would like to install it on my Mac running macOS Sierra. I have the serial number. I have found the download for PS CS5 but when I click "Install" I get an error. There seems to be a problem with verification and signage.





Widerrufene Autorisierung einer App

Eventuell liegt ein temporäres Problem mit der App vor. Obwohl die App von einem verifizierten Entwickler signiert wurde, wurde das Zertifikatfür die App widerrufen, was dazu führt, dass die App nicht mehr geöffnet werden kann.

Sehen Sie im Mac App Store nach oder fragen Sie beim Entwickler der Software nach, ob es eine aktualisierte Version für die App gibt.


a) is it possible to run CS5 from 2011 on current Macs? Is my license still valid?
b) what do I have to do to install it?
c) I currently have a PS CC subscription but I want to cancel it

Thank you

Andreas

    Legacy CS5 is not supported by Sierra.  The installation routine won't work as expected.  Below are some workarounds you could try.
