我在搬到新的笔记本电脑(Windows 10)后遇到了同样的错误.除了如上所述将 Copy Local 设置为 true 之外，我还必须为 .Net Framework 安装 Crystal Reports 32 位运行时引擎，即使其他一切都设置为在 64 位环境中运行.希望对您有所帮助.
I had the same error after moving to a new laptop (Windows 10). In addition to setting Copy Local to true as mentioned above, I had to install the Crystal Reports 32-bit runtime engine for .Net Framework, even though everything else is set to run in a 64-bit environment. Hope that helps.
