    You have to change your app pool to classic.net in iis7.

     

    It was very frustrating.

  • I was getting this error to, but after migrating web.config everything works, and you do not have to change you app pool to classic.net in iis7.

    I'm using ReportViewer v9.0, running on Vista x64.

  • What do you mean by migrating web.config.  I am using VS2008 report viewer and am getting this error when I call this from another program.
