其实上面给出已经说明了问题的原因。就这一段：SolutionThere are two main reasons why this error would occur.1) The Crystal Reports (CR) merge modules have been updated for the release version of Visual Studio .NET (VS .NET). They are now placed in a different folder and contain fixes from the beta versions.After having installed the release version of VS .NET on a clean machine, recreate/rebuild the setup project to include the new CR merge modules.2) The REGWIZ.MSM merge module requires a license key to be entered so that it can configure the deployment (target/client) machine. When this merge module is added to a setup project, the Properties window exposes a property called, License Key under the (MergeModuleProperties) property.The License Key requires the keycode that you receive after registering the product. When Crystal Report for Visual Studio .NET is registered, an email is sent with a keycode and a registration number. Copy the keycode into the License Key property, and then build the setup project.这个问题一般是在报表部署时发生的，如果不是因为这个，你要说明你是做什么操作时碰上这个问题，这样才便于大家来分析解决问题。
