Problem downloading CS5 onto MacBook Pro
I am trying to download a copy of CS5 onto a new MacBook Pro. I already have a registered copy on my iMac and need to put it on the mac book. We do not have a CD drive so am doing the digital download. It downloaded, but when I try to launch it comes up with this message. I am on Sierra 10.12.5 and have done the troubleshooting section advised by adobe but this hasn't worked. I have also contacted my Apple reseller and they have told me it should work and suggested I contact Adobe. Please Help!! I'm at a stand still at the moment! Thanks.
