Office Web Apps Missing/Required

Good Morning SharePoint Fam,

While I was out for some months, someone installed Office Web Apps into our current SP environment and installed it on the App server but not web server.  What is the best way to handle this to get SharePoint to stop alerting about "Office Web Apps" missing from Web Server.  Very small environment, One web, one app, one db server, Do i totally remove and start from scratch and make sure it's deployed to both servers and do psconfig?  Thanks n advance for any help
