PS Beta won't open

Hi, when I try to open Beta via the taskbar in OSX I get the message 'The application “Adobe Photoshop (Beta)” can’t be opened.' , if I try to open it via CC nothing happens at all. 

I can however open it fine if I use another adminsistrator account to login to my Mac, so I guess that means there's something stopping it in my login. I'e tried uninstalling and reinstalling, and using the CC remover tool on it, but nothing works.

Can anyone help please?
