How can I configure and deploy Crystal Report for .NET Framework 4.0.30319

Hi, I am trying to deploy a ASP.NET web application on IIS. My application has a Crystal Report(CR) which uses CR for Visual Studio (VS) 2010. It works fine on development server (press F5 in VS to run debug mode on development server). However, when I deploy it in IIS 7.5. It doesn't work.
I has download CR for VS 2010 runtime at and installed it already but no use. It doesn't appear any error message. It just print up "Error, Load report failed.". How can I deploy it? or at least how can I know what the error is for me to troubleshoot?
I'm running IIS 7.5 with .NET Framework 4.0.30319. I have installed "SAP Crystal Reports for Visual Studio 2010 Beta 2 - Redist (32 bit)". That text name appear in my "Programs and Features list".

I have solved this problem. It was missing the real Crystal Report file when publishing. There was a bug when converting .NET Framework 3.5 to 4.0 so that it made those files unable to publish. I have checked "bin" folder for dll and report files. Thanks for helping me.
Have you seen this document

Deploying Crystal Reports for Visual Studio 2010 Beta

What version of Windows on the server?

I did read those documents. However, about the first document, it brings up the trick to re-bind CR v14 to v12 but the runtime package for v14 is released already. Therefore, I installed it ( Moreover, the I tried to do those step in that document but all I got is a error that tell me I've used the old version (v12) while I have the new one (v14) installed.

I am running Windows 7 Ultimate (32 bit), IIS 7.5, .NET Framework 4.0.3x. I've installed CR for VS 2010 and runtime. Download from (1st and 2nd links). Is there any chance for me to view the clearer error message than "Error. Load report failed"

I have run on VS 2010 development server (F5 in VS 2010) and it works fine. It just doesn't work when I deploy on IIS.

Now, I uninstall "SAP Crystal Reports for Visual Studio 2010 Beta 2 - Redist (32 bit)". Delete all of folders in "C:\inetpub\wwwroot\aspnet_client\system_web\" then reinstall "SAP Crystal Reports for Visual Studio 2010 Beta 2 - Redist (32 bit)" again. In "C:\inetpub\wwwroot\aspnet_client\system_web\" now appear 2 folders "2_0_50727" and "4_0_30319". Both of them contain "crystalreportviewers14" folder. Then I go and restart IIS, refresh CR page. And I got the error "bobj is not defined" from Firebug on Firefox. What am I thinking now is somehow the CR cannot access to "C:\inetpub\wwwroot\aspnet_client\system_web\<whatever framework is>"

I copied "C:\inetpub\wwwroot\aspnet_client\" to my web application directory on IIS. "bobj is not defined" error is done. However, "Error. Load report failed" still there. Any help?
Can you pop into your code some form of

Catch ex as Exception
 write ex.Message to file or display on screen
End Try

That will normally give you the reason for the "Load report failed"
