    Hi anonymous userAgarwal-8271 ,
    You must ensure that every reference to the report viewer is the same. You need to delete the reference to the old report viewer control and add the new reference. You can refer to this article: https://stackoverflow.com/questions/42529104/failed-to-create-component-reportviewer-the-error-message-follows-system-run
    Then you can try to use the new report viewer control in your application.
    Best Regards,
    Joy
