Not able to run app on 2008 R2 server with Crystal Report

I am moving applications that prevopusly been running on windows 2000 server to our new internal web server running windows 2008 r2 (64 bit). I am running into CR issues which I have not been able to solve. Here is the scope:
Using Visual Studio 2008 .net framework 3.5. I have CrystalDecisions.CrystalReports.Engine.dll and CrystalDecisions.Shared.dll in my bin directory version 11.5.9709.1076. Crystal report .rpt is in my project.

When I try to run the application on the 2008 server I am getting error: An error has occurred while attempting to load the Crystal Reports runtime.

Either the Crystal Reports registry key permissions are insufficient or the Crystal Reports runtime is not installed correctly.

Please install the appropriate Crystal Reports redistributable (CRRedist*.msi) containing the correct version of the Crystal Reports runtime (x86, x64, or Itanium) required.
What do I need to install to get this working? I have installed CRBasicVS2008_redist_ia64, CRBasicVS2008_redist_x86 and also CRRedist2008_x64 but still getting the error.

Do I nedd to install something else ?

Thank you.
