I have a c# application that publishes to a server using click-once, so our company clients can run it. I upgrade my visual studio from 2010 to 2012. every thing is great so far and clients can run the application normally after my publishes. then I add a report viewer Item to my application and it runs on my pc well. but after publishing the clients face this error: unable to install or run the application. the application requires that assembly microsoft.reportviewer.ProcessingObjectModel version 11.0.0.0 to be installed in your GAC.
what should I do now, I search a lot but cant find a solution. thanks.
You will need to add the report viewer as a prerequisite. Here is a link to MSDN that describes what is needed.
