I am having problems with CS5 Photoshop. I recently updated my Mac to OS Sierra and now Photoshop doesn't work despite having no errors on my other Adobe programs. When I try to open Photoshop I get this error message: An expected and unrecoverable problem has occurred.


I tried to uninstall and reinstall, but my disc keep ejecting when it reaches 59% and the download I got from Adobe site won't open and I get this message:


 Install” can’t be opened. You should eject the disk image.

I need some help.

You may need to follow these instructions to run the installer on Sierra: https://helpx.adobe.com/creative-cloud/kb/install-creative-suite-mac-os-sierra.html

(Note: Sierra isn't an officially supported OS for CS5 which came out years prior. Use at your own risk)
