Thank you all for the feedback. Patrick, your workaround worked for me in Win 7. I had to follow a slightly different path to find the Photo Release.appinfo configuration file and delete it. In windows the path is:
C:\Users\username\AppData\Roaming\Affinity\Common\appinfo\Release\Photo Release.appinfo
I had to have admin authority to delete the file. This fixed the problem with Publisher-Photo interoperability.
