    I seem unable to upload any large-ish files (around 20mb up) in IE (any version) and Chrome. However, Firefox works fine.

    Using the development tools in Internet Explorer, I have noticed that a 404 error occurs. I have run though the following steps:

    Unfortunately,  This hasn't help.

    We are currently running under IIS 7.5


    <telerik:RadAsyncUpload ID="ruFiles" runat="server" Skin="" ControlObjectsVisibility="None"
                                    <Localization Select="" />

            <!-- the posted content for normal pages should be less than 1 MB.
                         File uploads are handled by the location attribute. -->
            <requestLimits maxAllowedContentLength="10485760" />
    <httpRuntime maxRequestLength="1073741824" requestValidationMode="2.0" />

    Hi Peter,

    The issue is most probably caused by the DisablePlugins="true" property that is set. Please try to remove it and upload the file again. You can also set the Chucnk size as it is shown in out on-line demo where this functionality is described.

    Hope this will help you solve the issue.
