    I have a problem with the reportViewer.
    A few months ago, I have created a project to create invoices.
    Now, I have to change some things, but my project is not working annymore.

    I could not fix it, zo I diceded to start all over again.

    The problem rises when I place a new report viewer. Then I get an error message.
    I get this message in every solution I got.

    Can someone help me, or direct me in the right direction?

    Hello Karin,

    Please check the project settings and whether the project meets the minimum Telerik Reporting System Requirements. Then run the Upgrade Wizard and verify all files are updated correctly.

    Also test to remove the current viewer control and add it as described in the How to: Add report viewer to a web page.

    In case the issue persists, please open a new support ticket where you can attach the problematic project for further investigation.
