Answer 1

1. Place this code in your app.config

    <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.2"/> </startup> 

2. If it would not work then download Crystal Report Runtime from this link http://downloads.businessobjects.com/akdlm/crnetruntime/clickonce/CRRuntime_32bit_13_0_1.msi

3. If again Crystal Report create some problem then right click on your project, open Properties, open Debug tab and check option Enable Unmanaged code debugging.

Answer 2

If you are running .Net 4 in VS2010, then you may need to add the following to your .config file (configuration section):

<startup useLegacyV2RuntimeActivationPolicy="true">
  <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>

If this doesn't work, then you need to upgrade to Crystal Report for VS2010 from this link .

Answer 3

如果您的系统中装有Visual Studio 2010，则不会安装Crystal Report，因为Visual Studio 2010中没有任何Crystal报表。要打开Crystal或.rpt文件，请安装SAP Crystal Report2010。它将从SAP对象Websit下载。

Answer 4

在应用程序配置中添加此代码

<startup useLegacyV2RuntimeActivationPolicy="true">  </startup>
