My suspicion is that you don't have the runtime for CR installed correctly. A lot of people make the mistake and install the runtime using the msi installer instead of the exe. The msi does not integrate CR with VS, the exe does. As Raphael pointed out in his comment, this posthas a very good thread and explanation by Ludek, who is one of the sharpest minds at SAP. You can download the exe here.
我怀疑您没有正确安装 CR 的运行时。很多人都犯了错误，并使用 msi 安装程序而不是 exe 来安装运行时。msi 不会将 CR 与 VS 集成，而 exe 会。正如 Raphael 在他的评论中指出的那样，这篇文章有一个非常好的线索和 Ludek 的解释，他是 SAP 最敏锐的头脑之一。您可以在此处下载 exe 。
Hope that helps,
