Report Viewer Configuration Error when upgraded from vs 2008 to vs 2013

Question

I have been assigned the task of upgrading our website from VS 2008 to VS 2013. I have come across several stumbling blocks on the way. I have upgraded the project from .Net 2.0 to 4.0 and the site runs fine except for the fact I get the following error when trying to view a report (the report itself does not display) :

Report Viewer Configuration Error

The Report Viewer Web Control HTTP Handler has not been registered in the application's web.config file. Add to the system.web/httpHandlers section of the web.config file, or add to the system.webServer/handlers section for Internet Information Services 7 or later.

Some reports have been converted by selecting the report in VS 2013 and then it asks Do you want to convert this report to the latest RDLC format? I hit ok and it seems fine. This error happens on all the reports. The upgraded one or the one I never opend in VS 2013. I also upgraded from Report Viewer 2008 to Report Viewer 2010. I have tried to add the Web.config suggestions in the error. I tried both entries and I have also tried each entry individually. Nothing seems to fix this. Everything else on the Web Site works fine.

Anyone got any suggestions? Do I need to upgrade Report Viewer to a later version? I am willing to try anything to get this to work. Thanks.

Looking in my VS 2013 project that uses report viewer, I'm using this report viewer NuGet package (as seen in the packages.config file):

<package id="MicrosoftReportViewerWebForms" version="11.0.0.0" targetFramework="net45" />

Then in my web.config, I have these two relevant section:

<system.web>
    <compilation debug="true" targetFramework="4.5">
        <buildProviders>
            <add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
        </buildProviders>
    </compilation>
</system.web>

and

<system.webServer>
    <handlers>
        <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
    </handlers>
</system.webServer>

Finally, I had to install ReportViewer on the server. That involved both ReportViewer.msi and SQLSysClrTypes.msi . Unfortunately, though I still have both on my machine, I don't know exactly the URLs for downloading them.

For ReportViewer, I've tried the Report Viewer 2012 Runtime from Microsoft, but it's not a binary match to what I have. Still, that seems like it's probably right and mine's just outdated. I'd start with that.

For SQLSysClrTypes.msi, it's basically the same situation. You can get it from the Microsoft® SQL Server® 2012 SP1 Feature Pack , but it's not exactly a match for what I used. Again, hopefully it's just been updated.
