Problems deploying a WinForms app that uses Microsoft ReportViewer

Question

I have published a WinForms application from Visual Studio 2010. It uses .NET 4.0. in the prerequisite dialog in Publish pane I selected .NET 4.0 Client Profile and Windows Installer 3.0. After publishing application to disk, I migrated it to client's computer which first installed .NET Client Profile and after reboot it gave following error message:

Unable to Install or run application. The application requires that assembly, Microsoft.ReportViewer.Common version 10.0.0 in global assembly cache first.

After this message the installation process exits. I'm using .NET's report in my project (not Crystal Reports).

You have to deploy the ReportViewer controls separately.

Check here on MSDN for more information: Deploying Reports and ReportViewer Controls

The ReportViewer control redistributable is a self-extracting file named ReportViewer.exe that includes an .msi and other files. You can find ReportViewer.exe at the following location:

%PROGRAMFILES%\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\ReportViewer\ReportViewer.exe

You can also download it from the Microsoft Download Center.

The type of control you are using determines where ReportViewer.exe should be run.

• For ASP.NET applications, run ReportViewer.exe on the Web server that hosts your application. This must be done by a server administrator.

• For Windows Forms applications, include the controls as an application prerequisite so that they are installed automatically with your application. You can use the bootstrapping application to automate this step:

  • Open the project properties page.

  • Click Publish, and then click Prerequisites.

  • Select Microsoft Visual Studio 2010 Report Viewer, and then click OK.

  • Publish the application.

During application installation, a check is performed on the local computer to see if ReportViewer is already installed. If it is not installed, the Setup program will install it.
