I made a careless mistake when running cumulative updates on a SharePoint farm and updated the web front end servers first before running on the app servers. Now the update files wont run on the app server. My WFE servers are updated service pack 2 and my app servers don't even have service pack 1 installed. When I try to run the update files on the app server it fails with "An error occurred while running detection."
Is there anything I can do at this point to force the update on the app server?
