ReportViewer not working on web server - asp.net

Question

Over the last month, I developed a WebForm app in C# with VS2013. It is working perfectly when I debug it and almost perfectly too once published on my iis 7.5 server on a App Pool using .NET Framework v4.030319. The problem is that the report viewer control doesn't work, exactly like this blog:
http://blogs.msdn.com/b/webtopics/archive/2009/02/10/report-viewer-toolbar-does-not-render-properly-on-iis-7-0.aspx
or the 49 other blogs I have read in the last 4 days... I tried every solution suggested and none of them worked. I am 100% sure it's not due to my report because just for testing, I created a basic report (just a textbox, no parameters, no datasource) and a new project with one page that load this report and I got the same problem.
Here is the concerned code in the web.config file:
<system.web>
<httpHandlers>
<add path="Reserved.ReportViewerWebControl.axd" verb="*" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" validate="false" />
</httpHandlers>
<authentication mode="None" />
<compilation debug="true" targetFramework="4.5">
<assemblies>
<add assembly="Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
<add assembly="Microsoft.ReportViewer.Common, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845DCD8080CC91" />
<add assembly="Microsoft.Build.Framework, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B03F5F7F11D50A3A" />
</assemblies>
<buildProviders>
<add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</buildProviders>
</compilation>
<httpRuntime targetFramework="4.5" />
[...]
</system.web>
<system.webServer>
<modules>
<remove name="FormsAuthentication" />
</modules>
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<add name="ReportViewerWebControl" 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>
And yes, I the mapping is also created on the server. Can someone help me fix this problem. I'm a little distraught.

Answer 1

I finally resolved it by installing the followings on the server:
dotNetFx45
ReportViewer 2010 Redistributable
Microsoft Microsoft System CLR Types for SQL Server 2012
ReportViewer 2012 Runtime
and restart it after even if it's not asked. After that, the reports were displaying properly. The fact that I didn't get any error messages wasn't helping very much. Also, the server is on prod so I couldn't restart it every time I want. Anyway, it's working now and that's the only thing that matters. Thanks.

Answer 2

For me these 2 mentioned below and no server restart worked
ReportViewer 2010 Redistributable
ReportViewer 2012 Runtime
Thanks
