Photoshop CS6: Won't open - Error 16 macOS Sierra

I have a full version of Photoshop CS6 installed on an iMac running OSX Sierra. The application was running fine until last night, when for some reason it crashed. Since then, all I get when trying to open it on either the Admin or other user accounts is Error 16, telling me to uninstall and reinstall the application. How could this be? What's going on here?

I have followed the instructions on the Help page (https://helpx.adobe.com/creative-cloud/kb/configuration-error-cs5.html#mac_os) relating to the SLSore and PCD folders. In fact, the settings in those folders were identical to those on the help page. Any ideas on what to do next would be appreciated. Please note, I'm not an advanced user, so simple terms would be much appreciated.

Well this might help if the other answers have not. I know it has helped me.

So first off open Terminal (You can type it in Spotlight)

Then copy and paste this command into Terminal:

sudo chmod -R 777 /Library/Application\ Support/Adobe

Press Enter and also input your password if asked.

Restart your Mac and see if that fixed it.

Gene, it worked! I have no idea what that command line did, but regardless, thanks so much. You turned a nightmare into a nothing more than a tiny issue. Cheers! Wayne

Glad to hear!

Simply put OSX has a permissions system, who can read, write and execute files and access folders. So the Photoshop Folder that you see talks to an invisible Application Support/Adobe folder. If those permissions are mangled, Photoshop throws up the mystery "Error 16" because it can't access what it needs to start up.

The command I gave you is a "under the hood" unix command that gives permissions to everything in that path, fixing whatever file had the mangled permission. It is Mac specific, not for Windows.

Kind of a sledgehammer approach, but is simple, does the job (in most cases) and does no harm.

This worked for a little while but, the problem reared its ugly head again after a couple of months.  Checked and the permissions were still set to 777.  The only thing that seems to fix it temporarily is to the let the display and screensaver kick off on their own, wait a couple of seconds, move the mouse to wake up the display, and then I can launch Photoshop.  I know, I know, doesn't make any sense but, I'm able to recreate this.  Not all of our cc2017 users are experiencing this so will try swapping out the Mac next...  again.

This may be a year late, but I just applied this sledgehammer to adobe CC and it worked wonders. Here's hoping I won't run into pc2mac63's problem. Thanks, Gener7!

Can I use this command for running macOS High Sierra and CS6 Extended?
I test macOS High Sierra 10.13.4 from external FW HD.
The message 16 come when I start the CS6 Extended.
The CS6 Extended is on internal SSD on iMac.
Before I go to macOS High Sierra on my iMac.
