Crystal Report errors when installing visual studio 2010 app

Question

I'm trying to install a Visual Studio 2010 application on two client's machines and I get a different error on each one.  Both errors point to Crystal Reports.
I have a feeling that I'm supposed to install something on the client's machines but I'm not sure what.
The first client's error says that CrystalDecisions.Windows.Form Version 13.0.2000.0 cannot be loaded.
The second client's error says that FlashControlV71. Version 1.0.3187.32366 needs to be installed in the GAC.
What am I supposed to install on the client's machines?  Or if that's not the problem, what is causing the errors?
This is my first visual studio app so I'm a complete newbie.
Thanks for any help or advice.

Thanks for your reply.  I installed the runtime (x64) and am now getting a new error on the first client's machine.  I think it's telling me that I installed the wrong version of the runtime.  The client is running x64t Win 7 so I chose the x64 runtime to install. 
System.TypeInitializationException: The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception. ---> CrystalDecisions.CrystalReports.Engine.LoadSaveReportException: 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.  Please go to http://www.businessobjects.com/support for more information.

The second client is running XP.  The error I'm getting on their machine is this:
     CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException:    Unsupported Operation. A document processed by the JRC engine cannot be opened in the C++ stack.
Thank you for your help.
