Exception Details:System.Runtime.InteropServices.COMException:Retrieving the COM class factory for component with CLSID {11bd5260-15b6-412d-80db-12bb60b8fe50} failed due to the following error:800736b1.

Find information on the Internet, found that a lot of people raised the problem, but the solution seems to be very few, I finally see the information is said to need Crystal Reports merge module, I was looking very confused, what is called merge module, check the data, MSDN is described in this way, Merge modules are the correct version of the report components and components that are installed with the application, and the Crystal Reports merge module must be included in the Setup project to be used to deploy the report. These merge modules are located in the following default locations: C:\Program Files\Common Files\merge Modules.

Can be downloaded from the http://www.businessobjects.com/products/dev_zone/net/2005.asp/ for the Crystal Reports for Visual Studio 2005 Merge module.

Computer Type	Project Type	Required Merge Module
32-bit	Windows Applications/Web sites	Crystalreportsredist2005_x86.msm
x64	Windows Applications/Web sites	Crystalreportsredist2005_x64.msm
IA64	Windows Applications/Web sites	Crystalreportsredist2005_ia64.msm

At that time I was depressed, because I installed the module of the CRYSTALREPORTSREDIST2005_X86.MSM, but still reported this error, and then I uninstalled this uninstall the reinstall, the problem solved. I think it seems to be the first time to install this module as if reported a mistake, then chose to ignore this error, may be so did not install successfully, so there are errors.

I hope my experience will be helpful to all of you. Thank you.
