If you developed crystal report in VS2008 for your web project and you need to deploy it on production or test server where VS is not installed. You need to install crystal runtime on server in order to view your report. Crystal runtime can be found very easily on development machine.

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\CrystalReports10_5

CRRedist2008_x64.msi (For 64 bit Machine)

CRRedist2008_x86.msi (For 32 bit Machine)

Could not load file or assembly ‘System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35′ or one of its dependencies. The located assembly’s manifest definition does not match the assembly reference. (Exception from HRESULT: 0×80131040)

I got this error when I am trying to create a report using Crystal Reports tool included in VS2008 with .NET 3.5 SP1. I also have VS2005 installed. I found perfect solution on the below website but must consider the scenario.
