ReportViewer error - The definition of the report " is invalid. Could not load file or assembly Microsoft.ReportViewer.ProcessingObjectMode

Question

I have ReportViewer in my project. When I create .exe of this file in InstallShield in Vsual Studio 2012 I add into Redistributables Microsoft ReportViewer 2010.

When I do install my app on Windows 8 - every ReportViewer displays it's report correctly.

I'm having problem on Windows XP the ReportViewer loads correctly but displayes this error instead of correct Report:

An error occurred during local report processing. The definition of the report " is invalid. An unexpected error ocurred in Report Processing.

Could not load file or assembly Microsoft.ReportViewer.ProcessingObjectMode. Version =11.0.0., Culture=neutral, PublicKeyToken=89845dc8080cc91 or one of its dependencies. this system cannot find the file specified.

I ensure you that in references I have added Microsoft.ReportViewer.Winfroms 11.0.0.0 and Copy Local = true.

How can I solve this issue?

Answer 1

I upvoted the reply marked as the answer because I was, infact, missing .dlls - but I did not fix it in the manner @Marek suggested. I'm using VS2013 and installing the Microsoft.Reporting nuget package fixed the problem. I would suggest to anyone with this problem trying this. That way, you automatically get all the dependencies.
